JIRA not sending eMail notifications

Question

I recently updated from Jira 7.2.6 to 7.6.2 and had the issue that Jira wasn't sending any eMail notifications. A few days later Jira 7.7.0 was released, so I updated to this version (2018-01-15) and notifications were now working again.

But since a few days, notifications seems to be broken again. We are not receiving any eMails from Jira when someone comments, transitions an issue etc...

I haven't changed anything on the notification schemes. Sending test mails in "System > Outgoing Mail" succeeds and the mails are delivered to my inbox.

What could this be, that notifications are working, but then stop working after some time?

Hi Shankar,

I just found an error message in the log files regarding a disabled plugin. I don't know if this has anything to do with the mail issue, but I uninstalled the plugin.

After uninstalling, mails still didn't work. So I restarted the server Jira is running on and now, mail notifications are being sent.

Maybe some background task hung?! I don't know. I hope it now just works...

Thank you for your help!

Hi Manuel,

It appears there is no clue as to what causing this issue and no log errors. Probably you might need to enable DEBUG mode and see if you can get any messages. Do you still have this problem now? If so, can you delete and recreate SMTP server again (in JIRA).  Is the issue happening to all projects and notification schemes? If there are multiple admins on JIRA, there may be chance that someone might did something to the notification scheme and that caused this issue. You can copy the problematic notification scheme and attach it to any test project and test again if you are still getting this problem.

thanks

Hi Shankar,

thanks for your reply.

I am using our company mail server, which has no restrictions in the number of mails being sended. As I said, sending test mails when logged into jira system preferences is working.

The mail queue in Jira is empty and I can't see any errors in atlassian-jira.log or atlassian-jira-outgoing-mail.log
