dovecot - Apr 2007 - Hot to get rid of \"DON\'T DELETE THIS MESSAGE\" messages?

I'm using Dovecot 1.0.0 (mbox) with Postfix 2.4 on my FreeBSD box, as a
pop3-only server (imap is disabled). All account mailboxes are accessed using
Outlook clients.

I've noticed that, whenever I'm retrieving mail with pop3, a
"DON'T DELETE THIS MESSAGE" is created in mbox. Although these
messages are never sent to client MUAs, I found them very annoying.

BTW I don't use (or used before) UW or Pine or any other c-client, therefore
I assume it's a Dovecot issue. Previously I was using Cyrus and never had
such a problem.

Any idea how this can be fixed?

It's a feature. You can't get rid of them. They're especially
important
with IMAP to avoid untrusted messages from messing Dovecot's UIDs.
