Postfix Question

[paulmorris at chch.org (Paul Morris)]

Hello List,

I am in search to a solution to get postfix to relay mail to two different
servers with the same domain name (ie. domain.org).  I believe that I have
it setup correctly now but I get the following error message in the mail
log:

Apr 24 15:38:04 gateway postfix/qmgr[30925]: 31A314262C1:

Mail comes into the system as user at chch.org.  In the alisas table, we have
it setup to forward as follows:

user:		user at server.domain.local
user2:	user2 at server2.domain.local

Even though it appears to be relaying the mail from the log above, I can't
see the attempted delivery in either of the mail server logs.  If there is
an expert at Postfix out there, we really need someone to come in to work
on this... hopefully it won't take more than a few hours to fix.  The two
mail systems we are trying to forward to are Exchange 2007 and FirstClass.

Thank you!!!!
