Hi All

Ok here is my setup.

Internal Exchange Server. NST 3.0 on it as a trial. Local users send/recieve via this.

Also have an external SMTP server hosted. This has a full 3rd Party Mail Server on it with duplicates of internal staff mailboxes and addresses. This has NST 3.0 purchased and running on it.

If internal server goes offline, all staff have a second POP account in Outlook which automtically checks mail on the external box and mail continues as normal.

Now. On a Second internal server I have a POP3 collector application. This collects mail from the hosted box and squirts it into internal Exchange all day long. So if anything on the remote server is missed by clients it is collected automatically at all times.

We are getting loads of spoofed emails using internal staff addresses. How can I block these without blocking legitimate mail which might be sent via a pop account by one of the internal staff?

Basically is there anyway to tell NST to not accept mail addressed domains it hosts?
