Just curious: why are 100% of Postfix servers "Version Other"?
The survey never proceeds beyond the "EHLO" greeting. That’s a shame,
because it means that about 50% of servers aren’t identified, whereas
some servers will give away their version number with a HELP, or
something like that. Anyway, some servers display the software name
at EHLO. And some of them also display the version number. Security
consultants don’t like that, so the display of software name or
version is often disabled. Not that it helps much, if at all.
So, perhaps Postfix never displays a version number.
Postfix doesn't display a version number by default, on the basis that
this information is of no relevance to a remote host trying to deliver
email to it. It can be configured to display a version number, but I
can't imagine why anybody would want to.
