[Lias] Postfix Problem.

[Ben Cooper]

Hey all,

I am having a problem setting up Postfix on RedHat 9. I have set it up
to reject_unknown_hostname for smtpd_helo_restrictions. Now when I
send
an email via telnet this is what i get:

> helo iona.qld.edu.au
...
450 <iona.qld.edu.au>: Helo command rejected: Host not found

I tried others like microsoft.com but it does the same thing. It
doesnt
seem to be doing a lookup.

Does anyone have any ideas?


Thanks,
