[logback-user] Help with SMTPAppender configuration

29 Aug 2008

      Hi
I'm unable to get the SMTPAppender working, I've got mail.jar and  
activation.jar on my classpath and I'm running an SMTP server on my  
localhost. When I generate log events of level ERROR no attempts are  
made to send messages according to my mail server logs.

I'm not sure how to go about diagnosing the problem as logback does  
not log messages about itself.
Any suggestions appreciated.
