Email are delivered with big delay

[Panagiotis Georgakopoulos]

Hello to everyone,

We are currently having an issue with our Jira installation. We are experiencing several hours delay of email delivery. In our configuration, the Mail Queue Service has Advanced Inteaval: 0 * * * * ?

Is this correct? What is the correct value that must me configured? 

Best Regards,

Panos

@Panagiotis Georgakopoulos, That cron expression is correct for a 1 minute run.  ie. 10:50, 10:51, 10:52, 10:53 ...

Check you outbound mail queue.  Are there a bunch of issues stuck?  If it's empty, it may be an issues with you mail server.

There are a few troubleshooting steps you can look at:

"A useful tip for debugging mail-related problems in JIRA is to set the -Dmail.debug=true property on startup. This will cause protocol-level details of JIRA's email interactions to be logged. Additionally, turning up JIRA's log level will show when the service is running and how mails are processed.

Common Problems

• If JIRA does not appear to be creating or sending emails or creating issues and comments from email, your JIRA installation could be experiencing OutOfMemory errors. Please check your log files for OutOfMemory errors. If there are OutOfMemory errors, please restart JIRA and investigate the errors.
• If you receive 'Mail Relay' errors, make sure you have specified the Username and Password in the SMTP Host section of JIRA's SMTP Mail Server configuration page."
