User comes into the office. "Are there any known issues with the mail servers at the minute, I've not receied any mail from someone I'm normally in frequent corrrespondance with." "I know at least one mail didn't get through I saw a reply but not the message"

Erk, randomly dropped mail wouldn't be a good thing.

Check the gateway exim logs, yup a mail came in...
Check the exim on the imap server, okay... it got sent to cyrus...
Check the cyrus logs "mail discarded" by a sieve filter.
Check the sieve scripts...
