hi, when i change the outgoing smtp connector to relay through my service provider instead of my servers dns the mail just goes in a queue. I am using sbs 2008 server with exchange 2007. I change it back and it runs fine. I have done this many times on 2003 servers without any issue. I have tested the connector on outlook in the pop3 settings and it works fine. I am wondering do i have to do anything else in exchange 2007 to enable it other than: going to organization conf, hub transport, send connectors and changing the settings on the network tab on the connect to go through a smart host. I used to be so much simpler on the previous version of exchange!
