Very true.

More likely a bug in how messages get picked up, scanned, and put in the 
mailbox. I haven't been able to reproduce the behaviour, but I *have* 
noticed that the problem doesn't present itself when "Max Children =1", 
and I've noticed it happen only when dovecot is reading the inboxes.

What I've done in the meantime when a corrupted message (or line within 
an mbox file) doesn't allow the user to read mail is:

1. Rename the mbox file
2. do the following
formail -s sendmail user at yourdomain.tld < renamed.mbox.file

Usually this means that if the user was using POP and leaving messages 
on the server for an X amount of days, those messages will be 
redelivered "as new".
