While the Mailer plugin does properly send email notifications, when using the Email Extension plugin, we're getting "535 Auth failed" errors. Both plugins are configured the same (same SMTP host, port, user/pass).
I have attached screenshots of the configurations for both plugins, as well as the DEBUG log from a test job showing the error.
[JENKINS-64852] Email Extension Plugin 535 Auth failed error prevents sending emails

added a comment - Thanks for reporting this rbovill. Are you using the latest version of Email Extension? Some issues with SMTP settings were fixed in 2.79 and 2.80, but nothing that sounds exactly like what you're describing. Would be helpful if we could come up with steps to reproduce the issue, or (sanitized) versions of working or non-working ${JENKINS_HOME}/hudson.plugins.emailext.ExtendedEmailPublisher.xml configuration files.

I was able to fix the 535 Auth failed error by creating all new SMTP credentials. But I don't understand why that would be necessary.
