Re: Setting up Exchange 2003 to work with a SendMail gateway

Probably the hardest part will be reconfiguring the user agents to pick up
mail only at the Exchange server. You'll also need to figure out what is
acceptable to you regarding picking up mail while external to your network
(currently they get it via Sendmail POP/IMAP I assume) although RPC/HTTP is
a nice feature to take advantage of.

As for mail routing that's pretty easy. You want a smart relay
configuration.
Exchange: Add a SMTP address to your users (recipient policy + any addresses
that are unique will have to be manually dealt with) for domain.com and
apply it to all users. Make it a primary address type and let Exchange know
your Exchange server is authoritative for that domain (it's a checkbox. See
the help files for more information). Don't remove the int.domain.com but
just make it a secondary address.

Inbound: You'll need to tell Sendmail (which version?) to deliver the mail
it receives to your Exchange server vs. local mailboxes. Depending on
version and your exact requirements, you may choose different ways of doing
this. You may want to just forward all mail that Sendmail receives that is
destined for your domain to your Exchange server. I don't see a reason to
rewrite any addresses based on your information, but that's possible.

Outbound: route all mail from Exchange to your sendmail servers for
delivery. In Exchange, you'll create a connector and configure smart host
delivery. There are KB articles on this as well as information in the help
files.

Is that what you're after? Or did I miss something?
