Hi all

I've had a 2007 Server running as a single site entity for about 9 months now and it's ran fine.  However another site has now had a server installed too, it has created the inter-site links according to everything I see, but it seems they cannot send their email to each other.

The queue shows 17 messages sitting there with the DNS query failed messages, with 1 message giving 400 4.4.7 Message Delayed.

I have set up no edge connectors as far as I'm aware.
