[Dovecot] mbox-rewrite errors

[T. Horsnell]

I've noticed a burst of about 12000 of these mbox-rewrite msgs in the log,
spread over about 10 minutes.
They are always for the same person (XXX'd out here), and have not occurred
before or since.
There's no evidence of device problems in the message log.

Do I need to worry?
I'm still using dovecot-0.99.11-4 on a RHEL4 Opteron box.
