Following up to an old mail...but since nobody has ever posted how
to get this working I imagine pretty much everyone who tried it is
confused :-)
This bit is fine:
> relay maildelivery {
> listen on $relayd_addr port 2525

> }
("interface XX" is not yet documented but it is needed
for "transparent forward").
Here is the problem:

> lo0 port 2525
Thanks to phessler for the clue; this must be done
with a divert-to rule.
So, with modern PF syntax:
pass in quick on $ext_if inet proto tcp from $netguard to \
66.159.112.123 port smtp divert-to lo0 port 2525
I'll try and come up with something for the docs.
