For my POP users, I didn't. I leave everyone's 'inbox' in /var/mail in 
mbox format. If a user connects via IMAP (Squirrelmail, etc.), folders 
in /home/%u are created and stored in maildir format, but their inbox 
stays in /var/mail in mbox format.

Dovecot also comes with convert-tool. For the users who had mbox files 
in their home directory, I used it to convert those to maildir format. I 
don't think the port installs convert-tool; I got it by doing 'make' in 
the dovecot port directory and manually copied it from there.
