We have configured Jira Service Desk 4.7.1 to access our support email box on an email server.
We don't allow automatic account creation. We like to have the correctly processed emails to be deleted from the mailbox but unsuccessfully processed ones to remain in the mailbox
So if we configure to download the emails using IMAP they are marked as read but not deleted or moved as described in the documentation.
If we switch the fetch method to POP they are deleted as we like to have correctly processed emails deleted. The issue that even not correctly processed emails are being deleted.
The log file says correctly: Failure - Signup is not currently available
Which is correct. But why does it delete the email after that? I would expect such mail should stay in the mailbox so we can check if it was a legitimate request.
