Oh, I was not aware that this feature exists.

I was just experimenting with the "O" flag in dovecot-uidlist to see how 
the conversion script can be updated.  I was wondering if this is only 
implemented for Maildir?

Our migration process involves:
   1) Converting the maildir from Courier using the Perl script
   2) Converting to mdbox using dsync -R backup

The POP3 ordering seems to get lost during the second step.
I.e., if Dovecot is set up to server POP3 mails from a maildir having 
"O" flags, the POP3 ordering is as intended.  After changing the 
configuration to mdbox format and converting the mails using dsync, the 
POP3 ordering is different.

Is this known or am I missing something?  (I tried Dovecot 2.1.1.)

Cheers,
Christoph
