Using mysql mean you have virtual users and not those pesky real unix accounts.
Yeah, I forgot to mention that. We use virtual accounts in mysql as well, and it works really well, making management a doddle.
It also depends on what hardware you have, spam and av scanning can be expensive.
Yes, true. We've found that using a virtual disk helps a huge amount with scanning for spam and viruses. Memory is relatively cheap these days, and considerably faster than a physical disk.
I mostly followed this howto http://genco.gen.tc/postfix_virtual.php but alter it for your own needs
If you want to do it yourself there's a cracker on the Gentoo web site:
http://www.gentoo.org/doc/en/virt-mail-howto.xml http://www.gentoo.org/doc/en/mailfilter-guide.xml
We've adapted that a fair bit but essentially that's what we do.
