The Exim setup on golug.org's site which has a very vanilla setup does
seem to be very slow to respond to connections on port 25.  However it
does respond back quickly on port 587.  Whether this is Exim or
golug.org's ISP, I don't know.

Since gmane.io's submission page tests for port SMTP, it is getting a
very slow response back to it is timing out, and failing to connect.
However, on port 587, golug.org responses back quickly with:

--8<---------------cut here---------------start------------->8---
$ telnet golug.org 587

I was just asking if you could also try port 587 when validating the
mailing list.  With the increased use of network security, I think
more sites prefer 587.  I'm not sure how you do your forwarding of NNTP
submissions.  If you don't do ESMTP I guess I am out of luck.
