Running Exchange 2003 on Sever 2000. I want clients to get mail from an external POP3 domain (boughtonarchitects.com) to their mailboxes and also be able to end external email via SMTP. All clients also need to be able to exchange email on an internal domain (bainet.local). How do I set this up? SMTP connectors? Virtual servers? This is so much different than Exchange 5.5 (just upgraded since we are planning on moving to Server 2003 Enterprise Edition). Need help quick! Our office is crippled!
