Depending on size of the organisation you are doing this for - the move 
is going to be well worth it. There are tools / scripts available that 
will help move from mbox to mdir.

ext3 works well for me on EL4, a few hundreds of thousand emails per day 
coming in over MailScanner into commodity h/w hosted CyrusIMAPD. Plus, 
way too many horror stories going around to even consider reiserfs on a 
production machine :)

The performance increase from wu-imap to cyrus-imapd is one thing that 
makes the shift worth making. I find it interesting that you are even 
considering wu-imap for a "hundreds of thousands" imap store.

How much of an effort is it likely to be rewriting the procmail rules as 
sieve filters ? Maybe worth scripting something ?
