My mistake. After watching the NFS packets we see the server/c-client definitely creates the lock. This makes sense to me anyway since what we are seeing doesn't appear to be a lock contention issue. The problem occurs if a mail client moves a message from one folder to "INBOX". At this point the IMAP server puts the message into MAILSPOOL/user (/var/mail/user) and then snarfs it back to the mbox. It's during this operation that we see the introduction of a significant number of null characters into the message, sometimes over 5MB (yes megabytes). The nulls always occur right before the From line of a message though they aren't always introduced. It's very strange behavior. I'm not entirely convinced the IMAP server alone is the problem, but after much analysis it and NFS are the only places to look.
I forgot to mention in my last mention that this is imap-2002d. Is this possibly fixed in 2004a?
Thanks for the quick reply.

Thanks for the tip. I've been hearing a lot about Dovecot and will check it out.
