Re: routing email

I'm still not sure...

Although we share an outside smtp address our internals are different. The
exchange server is exchange.system.com and the Unix server is
unix.system.com, so we actually are the authoritative response for our
addresses. The problem is everyones primary smtp is aliased to @system.com.
Currently exchange is smart enough to know that its own recepients exist and
sends that directly to their mailbox and users on the Unix system are sent
via MX record.

We also have another domain that we have several users on that is part of
the same exchange org.

We currently have an Internet Mail Connector that has 2 rules with cost of 1
*
@system2.com

1 of our mail servers is set as a bridgehead and it is set to use DNS
instead of a smart host. Is it possible to still have the server send mail
to the Internet with the exception of messages directed to @system.com.

You can do this by simply telling your Exchange Org that it's not
authoritative for all email delivered to that address (in your Recipient
Policy) and then create a Connector for your domain with your Exchange
server as the bridgehead and the Unix server as a smarthost.

This will deliver all unresolved mail from Exchange Org to the Unix server -
it will be responsible for generating NDRs.

Our environment has 2 different mail systems on the same domain. We have
a
Unix based mail system and an exchange 2003 mail system. Currently the
way
mail flows is it comes into our spam gateways and then is delivered to
either
mail system depending on which system (exchange.system.com or
unix.system.com). From the outside though all mail is sent to system.com.
If we are sending messages between systems then mail is being sent to the
gateways and then directed to the other server. This is because our mx
record points to the gateways. What I am looking to do is have all mail
that
is to be delivered to the unix server be delivered directly to it. The
problem is I am not sure how I can do this without sending messages that
should stay locally to the unix system since all mail is sent to
system.com.
