I am performing final tests for outbound and inbound email with new Exchange 2007 Server via telnet. Public DNS "MX" records still not pointing to this server for "live" email, I want to make sure everything works before I "flip the switch".
I can telnet into the Exchange Server remotely and locally. Using the command line I can get the Exchange Server to accept an inbound email, and route it to my Mailbox - it works perfectly.
Outbound, however, is still not working. When I try to send mail from my user account, and I put in the external email address I want the mail to go to, I get the 550.7.1 "Unable to relay" message. I thought I had all the proper settings in my connectors, but here's what I have:
1) In the Organization config, under Hub Transport, in Send Connectors, I created one called "Send to Internet"... on the Network tab of the properties I have checked: "Use DNS "MX" records to route mail automatically" and at the bottom I have also checked: "Use external DNS Lookup settings on Transport server"
2) In the Server config, under Hub Transport, in the top pane SMTP properties, on the External DNS Lookups tab, I have checked: "Use these DNS servers" and I have entered the IP address of a server that is authorized for me to use by my Web Hosting company.
What else am I missing? Why won't outbound email go out?
Thanks for all help.
