Ok, this is a serious newbie question. I just set up Exchange Server Enterprise on a domain machine, and I can send out mail (SMTP) with no problems to a good working e-mail account that is not part of my domain. But when I try to send mail to a domain e-mail from an outside account, it never gets there. How does the mail actually get from one SMTP server to our POP3 Server, and do I have to do any special setup? Thanks in Advance...
