I get the same thing when I test that way. Is there a PIX firewall between

exchange and Internet? I can run the test from inside and it works fine

The banner your seeing is from a PIX Firewall with the SMTP Fixup protocol

enabled. This is blocking all but the basic SMTP verbs (commands) and will

not allow ESMTP functionality. It is recommended that you disable the SMTP

Fixup protocol on the PIX for any ESMTP Mail servers according to Cisco's

website:
