dovecot - Jun 2007 - dovecot help

Hello,
 
I have a mail server which I upgraded yesterday.  
 
OLD:
Redhat 9
sendmail (very old version)
UW ipop3d
usermin with readmail module for webmail access (very old version)
 
NEW:
Fedora Core 6
sendmail 8.13.8
Usermin for webmail again
dovecot 1.0.0

# /etc/dovecot.conf
protocols: pop3
login_dir: /var/run/dovecot/login
login_executable: /usr/libexec/dovecot/pop3-login
mail_location: mbox:/home/%u/mail:INBOX=/var/spool/mail/%u
mail_executable: /usr/libexec/dovecot/pop3
mail_plugin_dir: /usr/lib/dovecot/pop3
pop3_uidl_format: %08Xv%08Xu
auth default:
  passdb:
    driver: pam
  userdb:
    driver: passwd

 
Everything is working great, besides a few glitches here and there. However,
When accessing mailboxes via webmail (usermin) an email shows up with a
subject of DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA. As far as I
can tell, this is an IMAP folder directory portion of the mailbox file that
should be hidden.  
 
We don't use IMAP at all, and it is confusing people when they see this
message that never was in their webmail before.

Anyone know how to hide, remove or otherwise fix?
 
Thank you in advance.
 
Andy

Do these messages have X-IMAP: header? They should. And if they do, they
should not be visible with Dovecot v1.0.

Not really. They're created just the same with POP3. But in either case
they shouldn't be visible to users.

The message does have the X-IMAP Header intact.(X-IMAP: 1183060687
0000000002)  The email is hidden when using a pop3 client(doesn't download
it), or telnetting an account and using the LIST command.    The problem I
am having is that within webmail (read mail module of usermin) it doesn't
hide the message.  I think Dovecot is doing everything correctly, but more
so usermin is not registering that the message should be hidden, and I don't
know how to fix it.
