Just to brief on my setup:


We have AD forest corp.in and under that abc.corp.in and xyz.corp.in , we have exchange 2003 sp2 on windows 2003 sp2 currently, we are in process to move to exchange 2007. So we doing the testing.


I have installed first CAS/HT/MB exchange 2007 server in abc.corp.in domain. There is no issue. All are exchange 2007 sp2 on windows 2003 64 bit.

Now I installed first CAS server in xyz.corp.in domain, now problem is this server is trying to connect to exchange server in abc domain to learn the topology, but we have a firewall between these two domains, i.e between abc and xyz.


Now my management do not want to have any connectivity between these two domains, but we have to utilize gateway servers in abc domain for all our external mails. The reason why we don’t want full connectivity is abc domain is owned by service provider and we currently work on decentralized administrative model. Not sure what is the connectivity between exchange 2003 servers in these two domains, I am checking on this, this might give me some idea as well.

So given this scenario is it possible to open only SMTP port between HT of xyz domain to HT or edge of abc domain without opening any other ports for the other exchange server communication .


Hope this info is sufficient , can anyone please advice on this
