Exchange 2003 address space

Hi all,

What do I use for address space in a routing connector, I currently have ‘*’ and that allows me to send emails from outlook, but I changed it to ‘*mainaddress.co.uk’ (which would be our email address (incoming)) but that just bounces back the emails I try to send with a DNS error.

I want to make sure no-one can use us as a relay to send spam.

while our email address is one thing our domain email (internal email address) is something else, I have tried both but can’t get it to work and wondered if someone might have some ideas on how to get this to work.

Thanks in advance.
