Yes, we are using mbox format. We allow both pop3 and imap connections as well. We host almost 1000 domains on the same box. Most mailboxes are set to 3-5mb quotas, while others are 20mb. The exim queue has nearly 20,000 messages sitting in it (spam , email to users who dont have a mailbox setup, etc), could this be related?

Thanks,
John

Looks like you are using mbox format? Only one process can write to these files at a time, so you are probably looking at a conflict between exim and your POP and/or IMAP server (which is?). Guess: Are these users keeping an IMAP connection open all the time, or have very large inbox files and POP very frequently?
