We are running an Exchange 2007 server as part of the SBS2008 platform. We are also behind a SonicWall firewall. I've been thrown into administering the servers and need a little help.
We are switching from Exchange Defender to Webroot. Everything is setup on the Webroot servers, now I just have to point all traffic to go through their servers.
I have the mx records updated and they should be replicating now. I thought I could go into the exchange server and replace outbound.exchangedefender.com with post51.us.emailfiltering.com and everything would be ok, but my first test message just sat in the queue until I place the exchange defender server back into the smarthost field. I must be missing something somewhere? Do I have to create another connection piece????
I believe I also have an outbound lan-wan access rule in place to allow internal mail to pass on to the webroot servers.
