Hi,
We have two exchange servers in one AD. Various domains are hosted on
both servers but there are two prime domains company1.com and
company2.com... all incoming email from exim is passed to company1.com
server and all outgoing email goes out through company2.com and then
passed onto to another exim relay for outgoing.
Where I am having the problem now is that in /etc/aliases I have tried
support@???: supportalias1@???
support@???: supportalias2@???
this does not work and I get an invalid user when trying to send mail
in.
The only way around I that I can think of if having a dedicated account
in /etc/aliases and exchange
support: supportalias@???
And having the support@??? exchange account then filter and
forward to the appropriate support account for company1 and company2...
Rather sloppy, but at this point it is the only thing I can think of. If
there was only one domain this would be simple. I am limited in the
options provided for exchange 2003 and 2007 as we still run exchange
2000... ugh.
Thanks again for all the options and responses... greatly appreciated.
Jeff

Hmm. Can you tell me about how exchange is set up in your case? Are
you having one domain's email sent to one exchange server and then the
other domain's email sent to another exchange server? Is this all
wrapped up in one Active Directory? If so, I'd probably just have both
domains in that callout file. Then, Exim4 should still query the
exchange server you are relaying to for either address. Let me know if
I'm missing something about your setup.
