Hey everyone. Long time lurking, first time posting. I have a problem I hope you all can help me with.

We currently have Symantec Brightmail running in our office and are moving away from it to Redhat Linux with Sendmail. We need to be able to route mail in the following fashion:

- All Inbound Local Mail needs to go to mail.example.com or smtp.example.com with no MX lookup.
- All Outbound Non-Local Mail needs to go to 3rdparty.relay.com.

Do any of you all know how to do this or can you point me to some documentation that can lead me in that direction?
