I'm working on getting OpenSMTPd on OpenBSD 7.0-release working
properly, and don't see any information about the special handling that
MSAs can/should do that MTAs shouldn't and don't see any obvious way to
tell OpenSMTPd to do this handling on the submission/submissions ports.
listen on 0.1.2.3 port 25 tls \
hostname mx.example.com pki $foo \
filter { "rdns", "fcrdns" }
listen on 0.1.2.3 port 465 smtps \
hostname smtp.example.com pki $bar \
mask-src auth <table>
Two different ports, two different ways of handling things.
