HELP: e-mail forwarding with multiple domains on single interface

HELP: e-mail forwarding with multiple domains on single interface

Post by Adam Buhl » Wed, 10 Apr 1996 04:00:00



Hello Sun gurus,
    I've got a Sun box (Solaris 2.4) that is hosting a few different
domains (each with unique IP address).  I'm trying to set it up so that
people can receive mail at any of the domains through the same machine.
The main domain works fine (the main original IP address of the box), but
all of the additional domains I've added give "Error 554 - MX list points
back to original domain".  I've read up on Sendmail and tried to research
this as much as possible, but I can't seem to get that error to go away.
    Does anyone out there have any experience with this sort of thing?
    Any help would be tremendously appreciated.
    thanks,
    Adam Buhler

You need to edit sendmail.cf and add to the Cw macro all the domains
your system receive mail for.

Example:

Cwdrawbridge.com foo.com bar.com foobar.com

Where foo.com, bar.com and foobar.com are the other domains.

NOTE: the Cw macro might not be in your sendmail.cf file.  Just add it
near the top, maybe right after the Dj macro.

1. multiple virtual email domains on a single IP - possible?

Running RedHat v7.0, and trying to share a single IP for multiple
virtual Email domains, but having difficulty with it. Setting up
Apache is a breeze, no problem at all.

So, for an example, I have 1.2.3.4 dedicated to my system, and want
domain1.com and domain2.com hosted on that IP address.

So I create user "john" on domain1.com and domain2.com, and send a
simple test message to each account.

If I set my Email program to conenct to domain2.com, I download the
message from domain1.com.

So I change the passwords, and send another test message. Now I get an
error saying my password is wrong - even though I'm telling it to
connect to domain2.com, it's still connecting to domain1.com, I
*think* because of the shared IP address.

I need a workaround. Any suggestions are welcomed.
