we are using EXCHANGE 2007 in a SCC failover cluster.
Two domains are connected to the exchange server.
We have no problems with the domain 1 to receive emails, the emails arriving in one minute.
But from domain 2 we have major delays. The biggest delay was 19 hours.
Domain 2 has no exchnage server.
The exchange server belongs to domain 1.
But both domains are connected to the same firewall and therefore we just use a DNS forwarder to locate domain 1 from domain 2.
