This might be a tough thing to figure out but i have to give it a try.
With no changes i am aware of, my jenkins just stopped sending out e-mail notifications. I use jenkins 1.609 and email extension plugin 2.40.5. Jenkins runs as a service using a service-user who also has the rights on the server to send e-mails. Ports to our smtp-server are unlocked. Used telnet for testing that everything works as expected. SMTP-server works fine, so it has something to do with jenkins and i cant figure out what is going wrong. When i use the test-feature that jenkins offers i get: javax.mail.AuthenticationFailedException: 535 5.7.3 Authentication unsuccessful which tells me that either user or pw is incorrect, but i've checked many times, it's setup correctly. Can anyone help out with this? After decrypting the password i can safely say that jenkins does save the password correct. Pw is set to not expire, because of reasons like this. Checked anyway, but its working as intended. I also installed the Powershell-Plugin to test if Jenkins would send a mail using the script. I created a job that sends a mail using the powershell script and another mail right after using the mailer plugin. Script works fine, mailer plugin fails. I asked the same question on Stack Overflow, it did not solve my problem sadly. Any help is greatly appreciated! -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
