/**
 * An IMAP protocol provider for the Jakarta Mail API
 * that provides access to an IMAP message store.
 * Both the IMAP4 and IMAP4rev1 protocols are supported.
 * Refer to 
 * RFC 3501
 * for more information.
 * The IMAP protocol provider also supports many IMAP extensions (described below).
 * Note that the server needs to support these extensions (and not all servers do)
 * in order to use the support in the IMAP provider.
 * You can query the server for support of these extensions using the
 * {@link org.eclipse.angus.mail.imap.IMAPStore#hasCapability IMAPStore hasCapability}
 * method using the capability name defined by the extension
 * (see the appropriate RFC) after connecting to the server.
 * 

 * UIDPLUS Support
 * 

 * The IMAP UIDPLUS extension
 * (RFC 4315)
 * is supported via the IMAPFolder methods
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#addMessages addMessages},
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#appendUIDMessages appendUIDMessages}, and
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#copyUIDMessages copyUIDMessages}.
 * 
 * MOVE Support
 * 

 * The IMAP MOVE extension
 * (RFC 6851)
 * is supported via the IMAPFolder methods
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#moveMessages moveMessages} and
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#moveUIDMessages moveUIDMessages}.
 * 
 * SASL Support
 * 

 * The IMAP protocol provider can use SASL
 * (RFC 4422)
 * authentication mechanisms on systems that support the
 * javax.security.sasl APIs.
 * The SASL-IR
 * (RFC 4959)
 * capability is also supported.
 * In addition to the SASL mechanisms that are built into
 * the SASL implementation, users can also provide additional
 * SASL mechanisms of their own design to support custom authentication
 * schemes.  See the
 * 
 * Java SASL API Programming and Deployment Guide for details.
 * Note that the current implementation doesn't support SASL mechanisms
 * that provide their own integrity or confidentiality layer.
 * 
 * OAuth 2.0 Support
 * 

 * Support for OAuth 2.0 authentication via the
 * 
 * XOAUTH2 authentication mechanism is provided either through the SASL
 * support described above or as a built-in authentication mechanism in the
 * IMAP provider.
 * The OAuth 2.0 Access Token should be passed as the password for this mechanism.
 * See 
 * OAuth2 Support for details.
 * 
 * Connection Pool
 * 

 * A connected IMAPStore maintains a pool of IMAP protocol objects for
 * use in communicating with the IMAP server. The IMAPStore will create
 * the initial AUTHENTICATED connection and seed the pool with this
 * connection. As folders are opened and new IMAP protocol objects are
 * needed, the IMAPStore will provide them from the connection pool,
 * or create them if none are available. When a folder is closed,
 * its IMAP protocol object is returned to the connection pool if the
 * pool is not over capacity.
 * 
 * 

 * A mechanism is provided for timing out idle connection pool IMAP
 * protocol objects. Timed out connections are closed and removed (pruned)
 * from the connection pool.
 * 
 * 

 * The connected IMAPStore object may or may not maintain a separate IMAP
 * protocol object that provides the store a dedicated connection to the
 * IMAP server. This is provided mainly for compatibility with previous
 * implementations of the IMAP protocol provider.
 * 
 * QUOTA Support
 * 

 * The IMAP QUOTA extension
 * (RFC 2087)
 * is supported via the
 * {@link jakarta.mail.QuotaAwareStore QuotaAwareStore} interface implemented by
 * {@link org.eclipse.angus.mail.imap.IMAPStore IMAPStore}, and the
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#getQuota IMAPFolder getQuota} and
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#setQuota IMAPFolder setQuota} methods.
 * ACL Support
 * 

 * The IMAP ACL extension
 * (RFC 2086)
 * is supported via the
 * {@link org.eclipse.angus.mail.imap.Rights Rights} class and the IMAPFolder methods
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#getACL getACL},
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#addACL addACL},
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#removeACL removeACL},
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#addRights addRights},
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#removeRights removeRights},
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#listRights listRights}, and
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#myRights myRights}.
 * 
 * SORT Support
 * 

 * The IMAP SORT extension
 * (RFC 5256)
 * is supported via the
 * {@link org.eclipse.angus.mail.imap.SortTerm SortTerm} class and the IMAPFolder
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#getSortedMessages getSortedMessages}
 * methods.
 * 
 * CONDSTORE and QRESYNC Support
 * 

 * Basic support is provided for the IMAP CONDSTORE
 * (RFC 4551)
 * and QRESYNC
 * (RFC 5162)
 * extensions for the purpose of resynchronizing a folder after offline operation.
 * Of course, the server must support these extensions.
 * Use of these extensions is enabled by using the new
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#open(int, ResyncData)
 * IMAPFolder open} method and supplying an appropriate
 * {@link org.eclipse.angus.mail.imap.ResyncData ResyncData} instance.
 * Using
 * {@link org.eclipse.angus.mail.imap.ResyncData#CONDSTORE ResyncData.CONDSTORE}
 * enables the CONDSTORE extension, which allows you to discover the
 * modification sequence number (modseq) of messages using the
 * {@link org.eclipse.angus.mail.imap.IMAPMessage#getModSeq IMAPMessage getModSeq}
 * method and the
 * {@link org.eclipse.angus.mail.imap.IMAPFolder#getHighestModSeq
 * IMAPFolder getHighestModSeq} method.
 * Using a
 * {@link org.eclipse.angus.mail.imap.ResyncData ResyncData} instance with appropriate
 * values also allows the server to report any changes in messages since the last
 * resynchronization.
 * The changes are reported as a list of
 * {@link jakarta.mail.event.MailEvent MailEvent} instances.
 * The special
 * {@link org.eclipse.angus.mail.imap.MessageVanishedEvent MessageVanishedEvent} reports on
 * UIDs of messages that have been removed since the last resynchronization.
 * A
 * {@link jakarta.mail.event.MessageChangedEvent MessageChangedEvent} reports on
 * changes to flags of messages.
 * For example:
 * 
 * 
 * Folder folder = store.getFolder("whatever");
 * IMAPFolder ifolder = (IMAPFolder)folder;
 * List<MailEvent> events = ifolder.open(Folder.READ_WRITE,
 * new ResyncData(prevUidValidity, prevModSeq));
 * for (MailEvent ev : events) {
 * if (ev instanceOf MessageChangedEvent) {
 * // process flag changes
 * } else if (ev instanceof MessageVanishedEvent) {
 * // process messages that were removed
 * }
 * }
 * 
 * 

 * See the referenced RFCs for more details on these IMAP extensions.
 * 
 * WITHIN Search Support
 * 

 * The IMAP WITHIN search extension
 * (RFC 5032)
 * is supported via the
 * {@link org.eclipse.angus.mail.imap.YoungerTerm YoungerTerm} and
 * {@link org.eclipse.angus.mail.imap.OlderTerm OlderTerm}
 * {@link jakarta.mail.search.SearchTerm SearchTerms}, which can be used as follows:
 * 
 * 
 * // search for messages delivered in the last day
 * Message[] msgs = folder.search(new YoungerTerm(24 * 60 * 60));
 * 
 * LOGIN-REFERRAL Support
 * 

 * The IMAP LOGIN-REFERRAL extension
 * (RFC 2221)
 * is supported.
 * If a login referral is received when connecting or when authentication fails, a
 * {@link org.eclipse.angus.mail.imap.ReferralException ReferralException} is thrown.
 * A referral can also occur when login succeeds.  By default, no exception is
 * thrown in this case.  To force an exception to be thrown and the authentication
 * to fail, set the mail.imap.referralexception property to "true".
 * 
 * COMPRESS Support
 * 

 * The IMAP COMPRESS extension
 * (RFC 4978)
 * is supported.
 * If the server supports the extension and the
 * mail.imap.compress.enable property is set to "true",
 * compression will be enabled.
 * 
 * UTF-8 Support
 * 

 * The IMAP UTF8 extension
 * (RFC 6855)
 * is supported.
 * If the server supports the extension, the client will enable use of UTF-8,
 * allowing use of UTF-8 in IMAP protocol strings such as folder names.
 * 
 * Properties
 * 

 * The IMAP protocol provider supports the following properties,
 * which may be set in the Jakarta Mail Session object.
 * The properties are always set as strings; the Type column describes
 * how the string is interpreted.  For example, use
 * 
 * 
 * props.put("mail.imap.port", "888");
 * 
 * 

 * to set the mail.imap.port property, which is of type int.
 * 
 * 

 * Note that if you're using the "imaps" protocol to access IMAP over SSL,
 * all the properties would be named "mail.imaps.*".

IMAP properties
Name
Type
Description
mail.imap.user
String
Default user name for IMAP.
mail.imap.host
String
The IMAP server to connect to.
mail.imap.port
int
The IMAP server port to connect to, if the connect() method doesn't
 * explicitly specify one. Defaults to 143.
mail.imap.partialfetch
boolean
Controls whether the IMAP partial-fetch capability should be used.
 * Defaults to true.
mail.imap.fetchsize
int
Partial fetch size in bytes. Defaults to 16K.
mail.imap.peek
boolean

 * If set to true, use the IMAP PEEK option when fetching body parts,
 * to avoid setting the SEEN flag on messages.
 * Defaults to false.
 * Can be overridden on a per-message basis by the
 * {@link org.eclipse.angus.mail.imap.IMAPMessage#setPeek setPeek}
 * method on IMAPMessage.
 * 
mail.imap.ignorebodystructuresize
boolean
The IMAP BODYSTRUCTURE response includes the exact size of each body part.
 * Normally, this size is used to determine how much data to fetch for each
 * body part.
 * Some servers report this size incorrectly in some cases; this property can
 * be set to work around such server bugs.
 * If this property is set to true, this size is ignored and data is fetched
 * until the server reports the end of data.
 * This will result in an extra fetch if the data size is a multiple of the
 * block size.
 * Defaults to false.
mail.imap.connectiontimeout
int
Socket connection timeout value in milliseconds.
 * This timeout is implemented by java.net.Socket.
 * Default is infinite timeout.
mail.imap.timeout
int
Socket read timeout value in milliseconds.
 * This timeout is implemented by java.net.Socket.
 * Default is infinite timeout.
mail.imap.writetimeout
int
Socket write timeout value in milliseconds.
 * This timeout is implemented by using a
 * java.util.concurrent.ScheduledExecutorService per connection
 * that schedules a thread to close the socket if the timeout expires.
 * Thus, the overhead of using this timeout is one thread per connection.
 * Default is infinite timeout.
mail.imap.executor.writetimeout
java.util.concurrent.ScheduledExecutorService
 Provides specific ScheduledExecutorService for mail.imap.writetimeout option.
 * The value of mail.imap.writetimeout shouldn't be a null.
 * For provided executor pool it is highly recommended to have set up in true
 * {@link java.util.concurrent.ScheduledThreadPoolExecutor#setRemoveOnCancelPolicy(boolean)}.
 * Without it, write methods will create garbage that would only be reclaimed after the timeout.
 * Be careful with calling {@link java.util.concurrent.ScheduledThreadPoolExecutor#shutdownNow()} in your executor,
 * it can kill the running tasks. It would be ok to use shutdownNow only when JavaMail sockets are closed.
 * This would be all service subclasses ({@link jakarta.mail.Store}/{@link jakarta.mail.Transport})
 * Invoking run {@link java.lang.Runnable#run()} on the returned {@link java.util.concurrent.Future} objects
 * would force close the open connections.
 * Instead of shutdownNow you can use {@link java.util.concurrent.ScheduledThreadPoolExecutor#shutdown()} ()}
 * and
 * {@link java.util.concurrent.ScheduledThreadPoolExecutor#awaitTermination(long, java.util.concurrent.TimeUnit)} ()}.
 * 
mail.imap.statuscachetimeout
int
Timeout value in milliseconds for cache of STATUS command response.
 * Default is 1000 (1 second).  Zero disables cache.
mail.imap.appendbuffersize
int

 * Maximum size of a message to buffer in memory when appending to an IMAP
 * folder.  If not set, or set to -1, there is no maximum and all messages
 * are buffered.  If set to 0, no messages are buffered.  If set to (e.g.)
 * 8192, messages of 8K bytes or less are buffered, larger messages are
 * not buffered.  Buffering saves cpu time at the expense of short term
 * memory usage.  If you commonly append very large messages to IMAP
 * mailboxes you might want to set this to a moderate value (1M or less).
 * 
mail.imap.connectionpoolsize
int
Maximum number of available connections in the connection pool.
 * Default is 1.
mail.imap.connectionpooltimeout
int
Timeout value in milliseconds for connection pool connections.  Default
 * is 45000 (45 seconds).
mail.imap.separatestoreconnection
boolean
Flag to indicate whether to use a dedicated store connection for store
 * commands.  Default is false.
mail.imap.allowreadonlyselect
boolean
If false, attempts to open a folder read/write will fail
 * if the SELECT command succeeds but indicates that the folder is READ-ONLY.
 * This sometimes indicates that the folder contents can'tbe changed, but
 * the flags are per-user and can be changed, such as might be the case for
 * public shared folders.  If true, such open attempts will succeed, allowing
 * the flags to be changed.  The getMode method on the
 * Folder object will return Folder.READ_ONLY
 * in this case even though the open method specified
 * Folder.READ_WRITE.  Default is false.
mail.imap.auth.mechanisms
String

 * If set, lists the authentication mechanisms to consider, and the order
 * in which to consider them.  Only mechanisms supported by the server and
 * supported by the current implementation will be used.
 * The default is "PLAIN LOGIN NTLM", which includes all
 * the authentication mechanisms supported by the current implementation
 * except XOAUTH2.
 * 
mail.imap.auth.login.disable
boolean
If true, prevents use of the non-standard AUTHENTICATE LOGIN
 * command, instead using the plain LOGIN command.
 * Default is false.
mail.imap.auth.plain.disable
boolean
If true, prevents use of the AUTHENTICATE PLAIN command.
 * Default is false.
mail.imap.auth.ntlm.disable
boolean
If true, prevents use of the AUTHENTICATE NTLM command.
 * Default is false.
mail.imap.auth.ntlm.domain
String

 * The NTLM authentication domain.
 * 
mail.imap.auth.ntlm.flags
int

 * NTLM protocol-specific flags.
 * See 
 * http://curl.haxx.se/rfc/ntlm.html#theNtlmFlags for details.
 * 
mail.imap.auth.xoauth2.disable
boolean
If true, prevents use of the AUTHENTICATE XOAUTH2 command.
 * Because the OAuth 2.0 protocol requires a special access token instead of
 * a password, this mechanism is disabled by default.  Enable it by explicitly
 * setting this property to "false" or by setting the "mail.imap.auth.mechanisms"
 * property to "XOAUTH2".
mail.imap.proxyauth.user
String
If the server supports the PROXYAUTH extension, this property
 * specifies the name of the user to act as.  Authenticate to the
 * server using the administrator's credentials.  After authentication,
 * the IMAP provider will issue the PROXYAUTH command with
 * the user name specified in this property.
 * 
mail.imap.localaddress
String

 * Local address (host name) to bind to when creating the IMAP socket.
 * Defaults to the address picked by the Socket class.
 * Should not normally need to be set, but useful with multi-homed hosts
 * where it's important to pick a particular local address to bind to.
 * 
mail.imap.localport
int

 * Local port number to bind to when creating the IMAP socket.
 * Defaults to the port number picked by the Socket class.
 * 
mail.imap.sasl.enable
boolean

 * If set to true, attempt to use the javax.security.sasl package to
 * choose an authentication mechanism for login.
 * Defaults to false.
 * 
mail.imap.sasl.mechanisms
String

 * A space or comma separated list of SASL mechanism names to try
 * to use.
 * 
mail.imap.sasl.authorizationid
String

 * The authorization ID to use in the SASL authentication.
 * If not set, the authentication ID (user name) is used.
 * 
mail.imap.sasl.realm
String
The realm to use with SASL authentication mechanisms that
 * require a realm, such as DIGEST-MD5.
mail.imap.sasl.usecanonicalhostname
boolean

 * If set to true, the canonical host name returned by
 * {@link java.net.InetAddress#getCanonicalHostName InetAddress.getCanonicalHostName}
 * is passed to the SASL mechanism, instead of the host name used to connect.
 * Defaults to false.
 * 
mail.imap.sasl. xgwtrustedapphack.enable
boolean

 * If set to true, enables a workaround for a bug in the Novell Groupwise
 * XGWTRUSTEDAPP SASL mechanism, when that mechanism is being used.
 * Defaults to true.
 * 
mail.imap.socketFactory
SocketFactory

 * If set to a class that implements the
 * javax.net.SocketFactory interface, this class
 * will be used to create IMAP sockets.  Note that this is an
 * instance of a class, not a name, and must be set using the
 * put method, not the setProperty method.
 * 
mail.imap.socketFactory.class
String

 * If set, specifies the name of a class that implements the
 * javax.net.SocketFactory interface.  This class
 * will be used to create IMAP sockets.
 * 
mail.imap.socketFactory.fallback
boolean

 * If set to true, failure to create a socket using the specified
 * socket factory class will cause the socket to be created using
 * the java.net.Socket class.
 * Defaults to true.
 * 
mail.imap.socketFactory.port
int

 * Specifies the port to connect to when using the specified socket
 * factory.
 * If not set, the default port will be used.
 * 
mail.imap.usesocketchannels
boolean

 * If set to true, use SocketChannels instead of Sockets for connecting
 * to the server.  Required if using the IdleManager.
 * Ignored if a socket factory is set.
 * Defaults to false.
 * 
mail.imap.ssl.enable
boolean

 * If set to true, use SSL to connect and use the SSL port by default.
 * Defaults to false for the "imap" protocol and true for the "imaps" protocol.
 * 
mail.imap.ssl.checkserveridentity
boolean

 * If set to false, it does not check the server identity as specified by
 * RFC 2595,
 * RFC 2830, and
 * RFC 6125.
 * These additional checks based on the content of the server's certificate
 * are intended to prevent man-in-the-middle attacks.
 * Defaults to true.
 * 
mail.imap.ssl.hostnameverifier
javax.net.ssl.HostnameVerifier

 * If set to an object that implements the
 * javax.net.ssl.HostnameVerifier interface then, this object
 * will be used to verify the hostname against the certificate.  Note that this
 * is an instance of a class, not a name, and must be set using the
 * put method, not the setProperty method.  The given
 * object will provide additional checks based on the content of the server's
 * certificate are intended to prevent man-in-the-middle attacks.  Defaults to
 * null.
 * 
mail.imap.ssl.hostnameverifier.class
String

 * If set, specifies the name of a class that implements the
 * javax.net.ssl.HostnameVerifier interface or an alias name
 * assigned to a built in hostname verifier.  A class name will be instantiated
 * using the default constructor and that instance will be used to verify the
 * hostname against the certificate.  The alias name "legacy" will
 * enable the "sun.security.util.HostnameChecker" with fail over to
 * the "MailHostnameVerifier". The alias name
 * "sun.security.util.HostnameChecker" or
 * "JdkHostnameChecker" will attempt to access the
 * sun.security.util.HostnameChecker via reflection. The alias name
 * "MailHostnameVerifier" will check server identity as specified
 * by RFC 2595.
 * The instantiated object will provide additional checks based on the content
 * of the server's certificate are intended to prevent man-in-the-middle
 * attacks.  Defaults to null.
 * 
mail.imap.ssl.trust
String

 * If set, and a socket factory hasn't been specified, enables use of a
 * {@link org.eclipse.angus.mail.util.MailSSLSocketFactory MailSSLSocketFactory}.
 * If set to "*", all hosts are trusted.
 * If set to a whitespace separated list of hosts, those hosts are trusted.
 * Otherwise, trust depends on the certificate the server presents.
 * 
mail.imap.ssl.socketFactory
SSLSocketFactory

 * If set to a class that extends the
 * javax.net.ssl.SSLSocketFactory class, this class
 * will be used to create IMAP SSL sockets.  Note that this is an
 * instance of a class, not a name, and must be set using the
 * put method, not the setProperty method.
 * 
mail.imap.ssl.socketFactory.class
String

 * If set, specifies the name of a class that extends the
 * javax.net.ssl.SSLSocketFactory class.  This class
 * will be used to create IMAP SSL sockets.
 * 
mail.imap.ssl.socketFactory.port
int

 * Specifies the port to connect to when using the specified socket
 * factory.
 * If not set, the default port will be used.
 * 
mail.imap.ssl.protocols
string

 * Specifies the SSL protocols that will be enabled for SSL connections.
 * The property value is a whitespace separated list of tokens acceptable
 * to the javax.net.ssl.SSLSocket.setEnabledProtocols method.
 * 
mail.imap.ssl.ciphersuites
string

 * Specifies the SSL cipher suites that will be enabled for SSL connections.
 * The property value is a whitespace separated list of tokens acceptable
 * to the javax.net.ssl.SSLSocket.setEnabledCipherSuites method.
 * 
mail.imap.starttls.enable
boolean
If true, enables the use of the STARTTLS command (if
 * supported by the server) to switch the connection to a TLS-protected
 * connection before issuing any login commands.
 * If the server does not support STARTTLS, the connection continues without
 * the use of TLS; see the
 * mail.imap.starttls.required
 * property to fail if STARTTLS isn't supported.
 * Note that an appropriate trust store must configured so that the client
 * will trust the server's certificate.
 * Default is false.
mail.imap.starttls.required
boolean

 * If true, requires the use of the STARTTLS command.
 * If the server doesn't support the STARTTLS command, or the command
 * fails, the connect method will fail.
 * Defaults to false.
 * 
mail.imap.proxy.host
string

 * Specifies the host name of an HTTP web proxy server that will be used for
 * connections to the mail server.
 * 
mail.imap.proxy.port
string

 * Specifies the port number for the HTTP web proxy server.
 * Defaults to port 80.
 * 
mail.imap.proxy.user
string

 * Specifies the user name to use to authenticate with the HTTP web proxy server.
 * By default, no authentication is done.
 * 
mail.imap.proxy.password
string

 * Specifies the password to use to authenticate with the HTTP web proxy server.
 * By default, no authentication is done.
 * 
mail.imap.socks.host
string

 * Specifies the host name of a SOCKS5 proxy server that will be used for
 * connections to the mail server.
 * 
mail.imap.socks.port
string

 * Specifies the port number for the SOCKS5 proxy server.
 * This should only need to be used if the proxy server is not using
 * the standard port number of 1080.
 * 
mail.imap.minidletime
int

 * Applications typically call the idle method in a loop.  If another
 * thread termiantes the IDLE command, it needs a chance to do its
 * work before another IDLE command is issued.  The idle method enforces
 * a delay to prevent thrashing between the IDLE command and regular
 * commands.  This property sets the delay in milliseconds.  If not
 * set, the default is 10 milliseconds.
 * 
mail.imap.enableresponseevents
boolean

 * Enable special IMAP-specific events to be delivered to the Store's
 * ConnectionListener.  If true, IMAP OK, NO, BAD, or BYE responses
 * will be sent as ConnectionEvents with a type of
 * IMAPStore.RESPONSE.  The event's message will be the
 * raw IMAP response string.
 * By default, these events are not sent.
 * NOTE: This capability is highly experimental and likely will change
 * in future releases.
 * 
mail.imap.enableimapevents
boolean

 * Enable special IMAP-specific events to be delivered to the Store's
 * ConnectionListener.  If true, unsolicited responses
 * received during the Store's idle method will be sent
 * as ConnectionEvents with a type of
 * IMAPStore.RESPONSE.  The event's message will be the
 * raw IMAP response string.
 * By default, these events are not sent.
 * NOTE: This capability is highly experimental and likely will change
 * in future releases.
 * 
mail.imap.throwsearchexception
boolean

 * If set to true and a {@link jakarta.mail.search.SearchTerm SearchTerm}
 * passed to the
 * {@link jakarta.mail.Folder#search Folder.search}
 * method is too complex for the IMAP protocol, throw a
 * {@link jakarta.mail.search.SearchException SearchException}.
 * For example, the IMAP protocol only supports less-than and greater-than
 * comparisons for a {@link jakarta.mail.search.SizeTerm SizeTerm}.
 * If false, the search will be done locally by fetching the required
 * message data and comparing it locally.
 * Defaults to false.
 * 
mail.imap.folder.class
String

 * Class name of a subclass of org.eclipse.angus.mail.imap.IMAPFolder.
 * The subclass can be used to provide support for additional IMAP commands.
 * The subclass must have public constructors of the form
 * public MyIMAPFolder(String fullName, char separator, IMAPStore store,
 * Boolean isNamespace) and
 * public MyIMAPFolder(ListInfo li, IMAPStore store)
 * 
mail.imap.closefoldersonstorefailure
boolean

 * In some cases, a failure of the Store connection indicates a failure of the
 * server, and all Folders associated with that Store should also be closed.
 * In other cases, a Store connection failure may be a transient failure, and
 * Folders may continue to operate normally.
 * If this property is true (the default), failures in the Store connection cause
 * all associated Folders to be closed.
 * Set this property to false to better handle transient failures in the Store
 * connection.
 * 
mail.imap.finalizecleanclose
boolean

 * When the finalizer for IMAPStore is called,
 * should the connection to the server be closed cleanly, as if the
 * application called the close method?
 * Or should the connection to the server be closed without sending
 * any commands to the server?
 * Defaults to false, the connection is not closed cleanly.
 * 
mail.imap.referralexception
boolean

 * If set to true and an IMAP login referral is returned when the authentication
 * succeeds, fail the connect request and throw a
 * {@link org.eclipse.angus.mail.imap.ReferralException ReferralException}.
 * Defaults to false.
 * 
mail.imap.compress.enable
boolean

 * If set to true and the IMAP server supports the COMPRESS=DEFLATE extension,
 * compression will be enabled.
 * Defaults to false.
 * 
mail.imap.compress.level
int

 * The compression level to be used, in the range -1 to 9.
 * See the {@link java.util.zip.Deflater Deflater} class for details.
 * 
mail.imap.compress.strategy
int

 * The compression strategy to be used, in the range 0 to 2.
 * See the {@link java.util.zip.Deflater Deflater} class for details.
 * 
mail.imap.reusetagprefix
boolean

 * If true, always use "A" for the IMAP command tag prefix.
 * If false, the IMAP command tag prefix is different for each connection,
 * from "A" through "ZZZ" and then wrapping around to "A".
 * Applications should never need to set this.
 * Defaults to false.
 * 
 * 

 * In general, applications should not need to use the classes in this
 * package directly.  Instead, they should use the APIs defined by the
 * jakarta.mail package (and subpackages).  Applications should
 * never construct instances of IMAPStore or
 * IMAPFolder directly.  Instead, they should use the
 * Session method getStore to acquire an
 * appropriate Store object, and from that acquire
 * Folder objects.
 * 
 * Loggers
 * 

 * In addition to printing debugging output as controlled by the
 * {@link jakarta.mail.Session Session} configuration,
 * the org.eclipse.angus.mail.imap provider logs the same information using
 * {@link java.util.logging.Logger} as described in the following table:
