@johnny I had a weird instance where a ticket was stuck in the imap inbox and kept re-generating creating duplicate tickets. I moved the email to the ITFlow folder to get it to stop.
If I run the cronticketemailparser, I get the message "Failed to process email - flagging for manual review." Error repeats and the count corresponds to the number of unread messages.
I set the option to only generate tickets from certain domains. The emails that are still in the inbox are marked as unread. I assume it's supposed to mark them as read and that's not working. Marking all message in the inbox as read clears the error.
What would cause an email to get "stuck" like that?
