Re: [Nolug] running a mail server with a Cox account

In postfix /etc/postfix/main.cf I have the following params:
myhostname = ipxxx-xxx-xxx-xxx.no.no.cox.net # replace xxx with public
                                             # cox IP address
relayhost = smtp.east.cox.net

Then in /etc/postfix/virtual
scottharney.com scotth
scotth@scottharney.com scotth
scott_harney@scottharney.com scotth

I pull down mail with fetchmail. mail.scottharney.com is elsewhere. I
address outgoing messages with my MUA as you see (ie. scottharney.com )
but if you look in the "Received: headers" you'll see something akin to
this:
Received: from ipxxx-xxx-xxx-xxx.no.no.cox.net ([xxx.xxx.xxx.xxx])
        by lakemtao03.cox.net
        (InterMail vM.5.01.04.05 201-253-122-122-105-20011231) with ESMTP id
        <20030805133756.VJQU23518.lakemtao03.cox.net@ipxxx-xxx-xxx-xxx.no.no.cox.net>
        for <nolug@joeykelly.net>; Tue, 11 Aug 2003 09:12:56 -0400

That from line in Received shouldn't have any warnings about UNKNOWN or
show a forward/reverse domain mismatch.

Just make sure that when someone does "dig -x your.ip.add.ress" that the domain
part matches the domain your mail server says it is in (ie. $myhostname or
$myorigin parameters in postfix) I can tell you how to do it
in qmail as well but I haven't worked with sendmail in a very long time (except
to replace it with qmail or sendmail).
