Move away from qmail to ?

Last week we setup a new mailserver, but we got stuck with some sort of libc-problem.
Now I'm wondering: is it a good time to leave qmail behind.
The package have never been updated, and after installation we need to make about a dozen patches.
This is our setup:
- assp in front for spam-control
- qmail as MTA, deliver to Maildir's with single UID
- Dovecot as pop3/imap-deamon (with mysql-support)
- clamav as antivirus (launced by qmail-files)
We have about 2000 Maildir's, 3500 virtual domains, 5000 dot-qmail-files.

Contra's for leaving Qmail:
- it has run for years without any real problems and is very good tuned now.
- Can a swith to another platform be easily made (mail is critical for our clients)
- Qmail has been integrated in our backoffice very widely (users can make their own emailadresses, mailboxes, turn on/off antivirus antispam)

Pro's for leaving Qmail:
-Qmail isn't been updated for years, so things like SPF, URIBL, have to be integrated with patches.
-store dot-qmail-files in MySQL-tables, so the server can be easylier split to more servers.

Because Maildirs looked to best thing for us (easy switchover), the options seemed to me Postfix or Exim.
Anyone any experience in this?
All advice is welcome!

I have installed Postfix from source just to get to know it. And what I can say is that it is well documented, seems to have all the options you need and works great with MySQL.

I can not say about Exim, since I have never tried it. If you decide to go with Postfix, these will be a must must:

Either one you decide to go with, I will be more than happy for you to share your experience.
