* Buffers log messages from DefaultLogger, and sends an e-mail with the
* results. The following Project properties are used to send the mail.
*
* MailLogger.mailhost [default: localhost] - Mail server to use
* MailLogger.port [default: 25] - Default port for SMTP
* MailLogger.from [required] - Mail "from" address
* MailLogger.failure.notify [default: true] - Send build failure
* e-mails?
* MailLogger.success.notify [default: true] - Send build success
* e-mails?
* MailLogger.failure.to [required if failure mail to be sent] - Address
* to send failure messages to
* MailLogger.success.to [required if success mail to be sent] - Address
* to send success messages to
* MailLogger.failure.subject [default: "Build Failure"] - Subject of
* failed build
* MailLogger.success.subject [default: "Build Success"] - Subject of
* successful build
*
* These properties are set using standard Ant property setting mechanisms
* (<property>, command-line -D, etc). Ant properties can be overridden
* by specifying the filename of a properties file in the
* MailLogger.properties.file property . Any properties defined in that
* file will override Ant properties.
