mail problem outside the office

[dst]

I use a Solaris 9 box to host our pop3 mail. From inside
the office all sending and recieving to all email is
fine. When attemping from outside the office while
sending to an email (that is not our company email) it
gets rejected. Like if I send to a yahoo, AOL, hotmail
account. What do I need to look at/adjust so we can send
and recieve email from all emails outside the office?

It may be an authentication issue. If you're not coming in from the local
SMTP domain, the POP3 server is probably denying the relay.

Check your account properties' Outgoing Server properties tab. Try selecting
the option to require authentication and use the same settings as the
incoming mail server.
