>Description:
I have made a rcNG script for qmail-smtpd, so maybe the qmail port maintainer want to import it ...

This script is capable of managing multiple instances of qmail-smtpd, for example, one for outgoing and one for incoming.

For each instance, you can specificy to enable or not qmail-scanner (you may want to disable it for outgoing mails...).

Of course, for each instance you need a tcprules file (.cdb) and you can use a rbl file, just place that files in /usr/local/etc/smtp/ and use following names: rbls-INSTANCE.conf and rules-INSTANCE.cdb
