[Gllug] MTA Config (postfix)

[Kristian Davies]

Just wondering... I'm testing restrictions in postfix using warn_if_reject,
so it just logs rather than bounce.

Someone sent a legitimate email from the walkers food snacks company..

Mar  5 15:11:27 mailgate postfix/smtpd[4146]: 74C6A1C082: reject_warning:
RCPT from unknown[213.1.246.22]: 450 <pbswmz00001.uk.walkers.co.uk>: Helo
command rejected: Host not found; from=<WalkersUser at walkers.co.uk>
to=<OurUser at elixir-studios.co.uk> proto=ESMTP
hello=<pbswmz00001.uk.walkers.co.uk>

Now... I can see two problems, 1) The node the email come from isnt
resolvable 2) The hostname isnt resolvable.


This is probably an example of something that is quite common, so i cant
make postfix too restrictive. :(

Isnt this really bad practice by such a big company.

Should i get in touch with them??  The only way to get in touch seems to be
sending them a fax.

Cheers,
Kristian
