Email notifications are delayed

[Oleg]

Hi!

Jira Server 8.8.0, CentOS 7, PostgreSQL 11.6. I use corporate internal SMTP server for outgoing emails. Default settings.

When I use email to users from admin page in JIRA it's happening instantly. But notifications about events from tasks are delayed to ~10 - ~15 min.

I read "Troubleshoot slow mail notifications in Jira server" but it not help me.

Mail Queue Service value: "0 * * * * ?"

I see in logs that it's not a network or mail server issue.

Example: event in task 2020-04-27 12:04, I received email 2020-04-27 12:11

In logs

Somewhat recently Jira starting batching email notifications in an effort to decrease the chattiness of Jira. Our system's interval is set to 10 minutes. You can check yours by accessing the Batching email notifications page (. or gg and then start typing Batching)

[Oleg]

Yes! Thank you! Problem solved!

Hi, I have the same problem with the delay of emails with notifications that are delivered in a time that varies from 10/15 minutes up to the hour, how did you fix the problem? (Batching disabled or set a particular value? I currently have 10 minutes) thank you very much

[Бородкин Олег]

Hi! Disabled.

[Roma]

Hi, after disabling the batch I noticed that the mail queue is emptied randomly between 5 and 11 minutes while it should be emptied after one minute. What can it depend on? what checks can be carried out? Thanks

[Oleg]

Check the https://confluence.atlassian.com/jirakb/troubleshoot-slow-mail-notifications-in-jira-server-397803670.html

Examine your logs as I described. Maybe it will help.

Hi, thank you very much for the link, I made all the checks but unfortunately, from the logs, the "mail queue service" starts on average in the interval that can go from 10 minutes up to 30; what can it depend on? is the delay in service 0 * * * *?

Thanks a lot for other indications

[Oleg]

Hi! Yes, I have "0 * * * * ?" in Mail Queue Service and disabled Batch. In log service starts every 1 minute. I didnt do any additional settings.
