Emails not being appended to tickets

Hi guys,

got an odd one - the mail fetcher is working fine according to the wizard as is outgoing mail. New requests are being emailed through, however any updates issued by ticket requesters via email are not being appended to the ticket.

Any ideas on when to start?

Additional Info:

Mail is accessed via IMAP - fetcher is set on the correct port, interval is 1min.IMAP is accessible, and the username and password are correct. This was verified by a telnet session to the server from the helpdesk server itselfThe error message in the system logs is as follows:

Mail fetcing is delayed ....due to start time and finish time is ZERO

- There is no clock skew between the mail server and the ServiceDesk server
- There are no large emails in the mailbox
- IMAP has been restarted on mail server with no result.
