Mail Fetch Failure

stefanclark

A few times our cron mail fetch has stopped working without any visible indication / error etc. In such cases our mailbox has been filling up and no emails have been fetched.

I ultimately fixed the issue, although not sure which of the two actions fixed the issue, or if it was a combination. I would have expected either to show as a WARNING or ERROR in the system log.

1) I deleted some obvious junk/spam emails from the mailbox directly. Not sure if these were causing the mail fetch to fail.
2) The oauth token had expired. Unsure if this caused the blockage, or if the token expired after failing to compete fetches.

Is it possible to get a verbose output from api/cron.php to try debug where the failure is occurring?

Token expired issue would be the cause as it wouldn't be able to authenticate to fetch mail. You will see such errors in the _email_account table in the last_error_msg column. We are hoping to add better logging for this in future updates so please stay tuned!

Hey @KevinTheJedi I had the exact same issue, and got inspired by @stefanclark solution to fix it. I basically moved the oldest email that had not been fetched and then, suddenly, the queue of pending emails was being processed again and all emails were finally fetched!

Why certain emails cannot be processed by OSTicket fetch rule, whats the cause for this like is it email subject, contect, body, attachment, size ?
Why OAuth plugin cannot skip stuck emails and process the rest of the emails?

For now on I'll keep an eye on the mailbox to see if anything gets stuck in the future, and I'll also check the details of the email that was blocking the queue...
