asked on
one domain, two different email MTA's (servers)
here is the scenario:
tow companies are merging: abc.com and xyz.com
A new domain is being created: 123.com
company "abc" has 250 users on Exchange 2003
company "xyz" has 2800 users on qmail server
The company does not want to deal with exchange liscences for 3000 users, so they want one domain with two different email servers.
The new domain "123" will be used for all users in the new company, so they want the following:
123.com mail goes to barracuda spam & virus filter
But then we have a problem, two mail servers behind it, sharing the same domain name... So basically you have mail account "shawn@123" that is on the exchange server, and you have "bill@123" who is on the qmail server.
How do I route or forward which email belongs to whisch server? one server I am just fine, but two on the same domain I haven't attempted before.
Thanks!

Thank you for the info, the rest of my server infrastructure wont be here for a couple weeks, so then I can set up a couple test boxes to figure out what is going to work best.
Thanks again for the excellent ideas!
Thanks again for the excellent ideas!
If you decide to go the route of letting exchange do the relaying and you have some more questions just let me know.

exchange : user@abc.com, make a custom recipient for the other users so that they have two email addresses, one user@abc.com, and one with user@abc.abc.com, use this to foreword to the qmail system.
i do not know qmail well enough to say how to control the reply address but this should work.
