      The email-ext plugin no longer sends messages, instead it hangs after sending DATA:

      10:48:34 Some error occured trying to send the email...check the Jenkins log
      10:48:34 Finished: SUCCESS

      Looking at the Postfix log in debug mode, I can see that it sends MAIL FROM and RCPT TO correctly, but after it sends DATA it does not send anything else. Eventually the connection times out and the exception above is reported in the log.

      The standard email functionality continues to work as normal.

      From postfix it only shows that it received 'DATA' but nothing more:

      I've added -Dmail.debug=true to the JVM options and I've also enabled debug mode for email-ext, but I can't seem to get any further information.

      Is there anything else I can do to help diagnose what's going wrong?

      Thanks very much,
      Jamie

          I'm concerned about the difference in the boundary info shown on the working and failing case. I'm not sure how the plugin would cause an issue there since this is just the JavaMail at this point.

          I've tried this on the LTS on Tomcat and it fails again - with just the default plugins and extended email enabled.

          I think this is one of those strange classpath problems in Tomcat, I started up Winstone, using the same JENKINS_HOME, re-built the job and the email was sent correctly.

          I'm not sure how to fix it within Tomcat though...

          I'll try under Tomcat and see if I can find anything.

          To test this I ran the exact same Jenkins installation under Winstone - it works perfectly, so I definitely think this is related to Tomcat.

          I'm still not able to replicate this even under Tomcat. The emails get sent just fine for me. Can you send me the test config you used?

          Do you have the security manager enabled in Tomcat?

          I finally figured out the problem, there were some EclipseLink JARs in $TOMCAT_HOME/lib which were apparently causing this. As soon as I removed them JavaMail worked correctly.

          Would it be possible to add something about that to the Ext-Email wiki page, just in case someone else has this issue?

          Many thanks for all of your help!

          Reporter had some jars that were causing issues.
