That sounds like the TPDA msg:delivery event

I'll need to look into that - exactly who is providing that message;
is it the receiving MTA rejecting the message? Agreed we need the
facility for them.

Doesn't matter; as you noted re. the name, it's now grown beyond just
the transport and needs a rename.

By all means; all contributions welcome.

Yes. Use the tcp:connect event; you get given the banner
and if you return a non-empty string for the expansion the
connection will be dropped.

If you use the transport option, *all* event types call the expansion.
It's up to you to do something appropriate for all types
(usually this will be "return an empty string" for all but the
ones you're interested in).
