Emailing coworkers who also using the same SBS server is no problem. The outgoing SMTP server recoginizes that their Inbox is on the server and delivers the email.
What about a coworker who is not onsite. They independently POP their email from the same POP server that the SBS POP3 connector does.
What currently is happening (by default) is that when a internal user wants to send a message to the external user they get a message something like “Undeliverable, user does not exist”.
How do I configure Exchange on SBS 2003 to send the email to the ISP for delivery?
