Convert Sendmail Email to Qmail

[webmaster at hpcaz.com]

QUESTION:
What is the best way to convert from Sendmail's mailbox format (mbox) to 
Qmail's (maildir)?  (Also moving from RedHat to FreeBSD--hence my post to 
this list. And, yes, I'm also posting to Qmail's list.) 

SITUATION:
I currently host a number of sites on RedHat 7.3 with Sendmail/LinuxConf as 
the MTA (LinuxConf is purly for vdomains). 

The Sendmail/LinuxConf pair are severely lacking features and usability I've 
come to like with Qmail/vmailmgr. 

However, with more than 40 domains and (in the neiborhood of) 600 users it'd 
be a tremendous amount of work to move them manually. 

Any help would be appreciated.
