An email "from" will say whatever a user's primary address is.

The confusion factor may be that an email will exit an Exchange
organization from the "nearest" Internet-enabled server regardless of
the originating server. That IP address may be .com or it may be .it or -- who knows? And it doesn't matter.

The From and Reply-To headers will still be correct for the user --
based on the user's primary address.

The user's primary address is based on recipient policy.

Subject: [exchangelist] Multiple E-Mail Domains

Hi all,

We are going through the process of consolidating IT systems from
several subsidiaries.  Each has operated semi-autonomously from an IT
perspective with their own email systems and domains.  We are trying to
simplify the IT structure and bring everybody into one data center with
one address book, etc.  But for geo-political reasons each of the
operating units would like to maintain their country designators -   .it etc.  The domain names are all registered, so it is only a
matter of changing the MX records to point to one location.  My
understanding of Exchange 2003 enterprise is that it is no sweat to add
organizational units and recipient policies to allow these other domains
to be accepted, but all outgoing email goes out from the master domain
.com instead of .it or  It seems strange that I would need to
run separate AD/Exchange environments for each.  Any ideas?

Thanks in advance.
