Hi all!
Would you think that could be possible to allow that service to
choose/override the smtpd_service ( specified in the
smtpd_service_name) and or redirect to a given listener ?
This could allow you to have different setting depending on some
aspects of the origin.
OpenBSD spamd already exists. Postscreen is not meant to duplicate it.

AFAIK, OpenBSD spamd is a *BSD only daemon that does
greylisting+tarpiting. Thats anti-spam stuff.
I meant for something more in the "mail management" area.
Having some daemon ( with any given business logic) that you could
use to chose the right listener to put your traffic in, is pretty much
valid.
nginx and haproxy already exist. Postscreen is not meant to duplicate them.
It could do dynamic assignation of different milter chains, message
size limits, content filters, etc
A front-end daemon that dynamically changes the configuration of
Postfix daemons? All Postfix configuration settings must come from
a file that is writable only by the super-user, otherwise the
configuration is not supported.
