postfix will be fine with sendmail options. postfix also support milters
and you can use something like mimedefang to do the same although you
will have write from scratch or go hunting.

postfix configuration is only complex because it offers more than qmail.
If someone were to look at your setup, it would be complex for them too
in the beginning.
djbdns has a ipv6 patch available. Unless you need dnssec, i don't see
why one needs to move off djbdns. But qmail or any patched ones is
another story. Just the need to stop qmail-send to do any queue
management is reason enough not to use qmail for incoming.
