I do recall that ident was one thing some MTAs wanted. Is that still
so? And if so, should I see a listen on it?
that is all *not* postfix related and for incoming mail you don#t
need anything than port 25
how is *that* related to mail?
http://en.wikipedia.org/wiki/Ident_protocol
There was a time some 20 years ago where E-Mail was a Unix thing only,
where servers try to identify the remote connecting with a "ident"
call and stall the connection until either succeed or timeout. This is
ancient behaviour not seen anymore, we have disabled the reject for
ident some 3 years ago.
And I brought up my first mailserver in '95 on an NT server. Probably
goes back that far! Just carried it forward all these years. Well
nothing is listening...
