Postfix and multiple domains

MasterC · 07-16-2003, 04:33 AM

Hello there!

Just wanted to comment on the thread I'm about to start:
Does anyone else feel "revealed" when they post up actual IP's and domains on their posts?

Ok, so here's my problem:

I have apache setup with virtual hosting of 3 domains (well 2 virtual and then the default). I, for the life of me, cannot figure out how to recieve email properly for 2 of the domains.

Let me break it down a bit:
All of these point to the same IP:
curvins.com (virtual)
masterc.no-ip.org (the default)
cherokeegods.com (virtual)

The first 2 (in apache) also have the same DocumentRoot (et al) and cherokeegods.com has a completely seperate layout (it's not mine, but I'm hosting it for a friend). I've been able (and have had 0 problems with it) to successfully setup recieving mail for curvins.com So I figured if I simply aliased masterc.no-ip.org to resolve to curvins.com in my Zone file (www.zoneedit.com is my DNS provider for curvins.com (and cherokeegods.com )and www.noip.com is my DNS for masterc.no-ip.org ) that sending email to:
xxxx @ masterc.no-ip.org
would simply resolve to:
xxxx @ curvins.com
But it would seem I am wrong (or possible just set something up wrong), because here is the message I recieve:

Code:

This is the Postfix program at host cooler.curvins.com.

I'm sorry to have to inform you that the message returned
below could not be delivered to one or more destinations.

For further assistance, please send mail to <postmaster>

If you do so, please include this problem report. You can
delete your own text from the message returned below.

                        The Postfix program

<xxxx @ masterc.no-ip.org>: mail for masterc.no-ip.org loops back to myself

If anyone has any ideas, or wants to see any of my setups, or needs anymore info, please let me know. I'll be happy to provide.

Thanks!

Cool

"mail for masterc.no-ip.org loops back to myself"

This would suggest that it is trying to forward the mail to another machine, because it thinks that it is not supposed to receive the e-mail. So it does a DNS request and finds that the mail is supposed to come back. So it gets stuck in a loop.

What you need to do is to setup Postfix to receive for all the domains you are hosting. The hostname for your machine (im guessing) is curvins.com, find the following line in your postfix config file:

mydestination = $myhostname, localhost.$mydomain

and add all the other domains you wish to receive for. So here is my line for extra domains i am receiving for (tanzofund.dyndns.org):

mydestination = $myhostname, localhost.$mydomain, tanzofund.dyndns.org

Then just set your DNS to send your mail to your IP and it should work.

Sweet! I was hoping it was something as cool as that

Thanks for the help! I'll give it a go later on, and I'm sure it'll work (it makes sense of course

).
