Sendmail: Multiple Virtual Domains
Hi,
I successfully use sendmail 8.13 for a domain (mydomain.de) as a mail-relay to MS Exchange Servers. I want to do the same thing for a second domain (mydomain.com) so you can send mails to user.name@mydomain.de and also to user.name@mydomain.com and they will both reach the same user.name@mydomain.de mail account on the MS Exchange server.
I followed the instructions for setting up virtual domains using the virtusertable and every else needed. When trying to send a message from the internet to a mydomain.com address I get the following sendmail log:
Oct 6 13:41:17 mailgate sendmail[26540]: i96BfHgl026540: <-- RCPT TO:<test.test@mydomain.com
Oct 6 13:41:17 mailgate sendmail[26540]: i96BfHgl026540: Milter: rcpts: <test.test@mydomain.com>
Oct 6 13:41:17 mailgate sendmail[26540]: i96BfHgl026540: --- 250 2.1.5 <test.test@mydomain.com>..
Oct 6 13:41:18 mailgate mimedefang.pl[24309]: MDLOG,i96BfHgl026540,mail_
Oct 6 13:41:18 mailgate sendmail[26544]: i96BfHgl026540: to=<test.test@mydomain.com
Mimedefang shouldn't be the problem. DNS shouldn't be, too. Sendmail first says "Recipient ok" but lateron gives the error "stat=Local configuration error"???
FILE virtusertable
...
@mydomain.com %1@mydomain.de
...
in sendmail.cf I have the FEATURE virtusertable (per hash) enabled
FILE relay-domains
mydomain.de
mydomain.com
To restart I use
makemap hash virtusertable.db < virtusertable
make -C /etc/mail
Then I restart sendmail and mimedefang
Any ideas?
Help is truly appreciated,
Kurt

Hi,
is it really necessary to change settings on the exchange server? Isn't there a simple way to have sendmail send all the mails going to
user.name@mydomain.de and
user.name@mydomain.com
to the same e-mail address on the exchange server? The exchange server is not under my supervision and I'm looking for a simple way: sendmail should provide this virtual .com-domain and the exchange server doesn't have to know this domain.
Sorry, but I'm not a pro in this field...still any further advice is appreciated.

Me again,
I just wanted to provide you with the full error logs:
Oct 7 09:48:06 mailgate sendmail[15952]: i977m490015941: SYSERR(root): MX list for mydomain.com. points back to mailgate.mydomain.de
Oct 7 09:48:06 mailgate sendmail[15952]: i977m490015941: to=<user.name@mydomain.com
Oct 7 09:48:06 mailgate sendmail[15952]: i977m490015941: alias postmaster => postmaster@mydomain.de
Oct 7 09:48:06 mailgate sendmail[15952]: i977m490015941: i977m690015952: DSN: Local configuration error
How can I make sendmail switch the TO address from any.name@mydomain.com to any.name@mydomain.de???
Thx a lot,
Kurt

> is it really necessary to change settings on the exchange server?
In this case, yes. Your server isn't relaying both of the domains to the exchange server. One domain is virtual and it doesn't exist on the exchange server. So you map addresses in that virtual domain to addresses in the real domain that the exchange server knows about with virtusertable. Once you have to do that with the virtual domain you need to do likewise for the real domain.

The trick that can also be used is a mailertable entry
say that the exchange is accepting mydomain.de
then just add
in
access
mydomain.de RELAY
and in local-host-names you have
mydomain.com
In virtusertable you have
@mydomain.com %1@mydomain.de
Last you have
mailertable
mydomain.de esmtp[ipaddress of exchange]

Hi,
thx for the tip! But it's still not working...
My access and virtusertable files are as you recommended.
In local-host-names I have
mailgate.mydomain.de
mydomain.de
mailgate.mydomain.com
mydomain.com
Plus I have the mailertable empty since the relaying of mails user.name@mydomain.de to the Exchange Server works (I guess that's because of the "MAIL_HUB" entry in sendmail.mc)
It seems as if sendmail would not change user.name@mydomain.com to user.name@mydomani.de (settings in virtusertable). Shouldn't sendmail first make this recipient changes and then try to send it to the Exchange Server?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
You can't use:
@mydomain.com %1@mydomain.de
in virtusertable if local-host-names includes "mydomain.de". That's a circular definition as the local-host-names file tells Sendmail that it is the mail server for the domain and the virtusertable tells Sendmail to send mail for mydomain.com to itself. In this case you must use a virtusertable defintion like I've described above and configure the exchange server to listen for mail addressed to the FQDN in addition to mail addressed to the domain.

Thx HalldorG!
sorry jlevie I wanted to split the points but didn't know how and since HalldorG provided the real answer and your comment was more like "helping myself to understand why"....I gave the points to HalldorG
Thx a lot to the both of you guys,

local-host-names:
mailgate.mydomain.de
mydomain.de
mailgate.mydomain.com
mydomain.com
virtusertable:
@mydomain. %1@exchg.mydomain.de
@mydomain.com %1@exchg.mydomain.de
relay-domains and mailertable need to be empty files. And you'll have to tell your exchange server to list for mail addressed to user@exchg.mydomain.de in addition to its default of user@mydomain.de. And, obviously, the Sendmail server has to be able to resolve the hostname (exchg.mydomain.de) via DNS or the local hosts file.
