Telnet between Hub Transport servers

I often find telnet a good way to diagnose SMTP problems.

Our Exchange 2007 environment has multiple AD sites each with their own Hub Transports.

Should I be able to send mail via telnet from one HT to another? Although I can initially telnet on port 25 to another Hub Transport server, I am unable to actual send SMTP mail.

Once i get to :

MAIL FROM: me@domain.com

I get an error saying that

"530 5.7.1 Client was not authenticated"

Any ideas?

Your default recieve connector does not have the anaoymous checked under the permissions tab...set this and you should be good to go

"Should I be able to send mail via telnet from one HT to another?"

You should be able to submit if anonymous is ticked, however, you still won't be able to relay outside unless you authenticate or amend security on the receive connector and that is quite normal and by default.
