On Centos the other reasonable choice would be to configure procmail to default to deliver in maildir format (should work for either sendmail or postfix) and Dovecot to expect that format, and use authconfig/pam to authenticate however you want. I think you'd have to create the home directories ahead of time though, and delete them when the account goes away.
PAM can auto-create home directories via pam_mkhomedir.so, which is included with CentOS. Auto-creation is typically associated with login activity (/etc/pam.d/login), but I wouldn't be surprised if it could be associated with Dovecot IMAP/POP access. The README is available via CVS:

I know it can do it as you log in, but in this case the mail delivery may come first. I'd assume you'd add a user to the network authentication system and send off a welcome email. And I don't think procmail will auto-create a maildir even if the home directory was already there.
