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?

I am having to page back at least 3 mailservers ago. I could replug in
my last one (which I have not erased yet) to see if it used it, but
definitely some time ago I remember having to enable ident for mail.
Now was it for MTAs or clients? I am going back at least 6 years here.
I doubt if I can find notes for it.
And yes, ident could query things like port 25 to see if it is mail.
Thinking back, now this may go back over 10 years and just being carried
forward. And my yahoo problem could well be they don't like the spf
rule that google wanted... Waiting for the mail admin to respond to the
ticket I opened last night.
