Lutz Huehnken commented on LBCLASSIC-323:

I haven't found the time yet to isolate the code where the error occurs from the bigger project it is contained in, but I'll post code and config snippets. Maybe something is so obviously wrong in there that it is sufficient.

The config - in this application, a separate logger category - "myproject.notifications" is used just to send e-mail notifications. 

In logback.xml:

<!-- smtp appenders for e-mail notifications  -->
<appender name="notifications" class="ch.qos.logback.classic.net.SMTPAppender">
	<to>deletedforlogbackjira at mailinator.com</to>
	<subject>Wichtige Meldung - Bearbeitung erforderlich</subject>
	<layout class="ch.qos.logback.classic.PatternLayout">
	<cyclicBufferTracker class="ch.qos.logback.core.spi.CyclicBufferTrackerImpl">
		<!-- send just one log entry per email -->

<!-- setup loggers -->
<logger name="myproject.notifications" additivity="false" level="INFO">
	<appender-ref ref="notifications" />

In the java code:

   private static final Logger notifier = LoggerFactory.getLogger("myproject.notifications");

   in some method
   /* not really an error, but error level is necessary to trigger mail sending */
   notifier.error("some message");

> After upgrading from 0.9.30 to 1.0.0, the ch.qos.logback.classic.net.SMTPAppender seizes to work. It just does not send any messages anymore.
> This behaviour has apparently been observed by others as well and is also described in this thread:
> http://old.nabble.com/SMTPAppender-mail-not-sent-%28logback-1.0.0%2C-JDK-1.5%29-to33164248.html
> It resumes working when - while making no other changes - logback is downgraded to version 0.9.30
