Postfix, and DNS corrent settings? for mail sending

Hi everybody!

First of all thank you for this first class hosting panel.

Sorry for my bad english. :slight_smile:

I have got a domain - - and subdomain -, and additional IP address. - ipn.umb.er1 - ipn.umb.er2

I’ve got an email address with parent domain - ->

When I sending an email from, and sender address is, my email already arriving from IP1, just the second Received contains IP2.

And the SPF record says neither permitted.

I configured sender_dependent on virtualmin ( postfix 2.9 ).

Email header is:

Received: by with SMTP id y6csp114868bkb;
Fri, 12 Apr 2013 14:05:16 -0700 (PDT)
X-Received: by with SMTP id so5mr9729707vec.6.1365800715596;
Fri, 12 Apr 2013 14:05:15 -0700 (PDT)
Received: from ( [ipn.umb.er1])
by with ESMTP id sx2si7545142vdc.32.2013.;
Fri, 12 Apr 2013 14:05:15 -0700 (PDT)
Received-SPF: neutral ( is neither permitted nor denied by best guess record for domain of client-ip=;
spf=neutral ( is neither permitted nor denied by best guess record for domain of;
dkim=neutral (bad format)
Received: from ( [ipn.umb.er2])
by (Postfix) with ESMTPA id 184C01E2F40
for; Sat, 13 Apr 2013 23:05:07 +0200 (CEST)
DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple;;
s=2013; t=1365887107;

So I have to send email with IP2, hostname from

What have to config?

Thank for helps.


you might need to check your rdns settings / ask your hosting provider to create an rdns record for you. Whilst you can send from multiple domains, unless your rdns record points to the canonical name of your server ie. (if you want it to be that) then you’ll have difficulty sending emails from various accounts.

A quick check to make sure your rdns is correct is sending an email from your server to Gmail – if it’s correct, Gmail will list the email as being via

Hope this helps!
