Here's my configuration:
Exchange 2000 server running SMTP tfor corporate mail.
Webserver (UNIX) running web/pop3/smtp and list server.
MX record in ISP's DNS points all mail to corporate Exchange server.
Web server DNS entry www.abcco.net
points to external interface routable address.
Externals normally send mail to email@example.com.
I need extrnals (and internals) to be able to send mail to: firstname.lastname@example.org
Do I need an additional MX record? And Exchange connector? I'm at a loss how to configure this.
I tried using an Exchange connector, but ALL SMTP was being routed through the web server and this is NOT a good thing.
