We Have a Exchange Server 2003 running on Microsoft SBS 2003.
Initially the server was set up to collect/receive mail driectly from the .co.uk domain - NOT POP mailboxes.
For a number of reasons, we have now had to change this.
We have set up POP collection for all exchange mailboxes/users and stopped the domain forwarding at the domain control panel with our isp.
We have also set up all necessary POP mailboxes at the domain control panel.
These POP boxes are working very well (Using Roundcube webmail).
Exhcange is also sending OK via its own SMTP.
The problem is that whilst exchange will collect email from a pop on any ANY other domain (we have tested successfully on several), it will NOT collect email from the original domain's pop boxes.
Is there something we are missing on the Exchange Server or SBS config that needs to be changed ?
Any help would be very gratefully received - My email is firstname.lastname@example.org.
