SMTP response "354 Ready, steady, go"
Posted on 2009-03-31
I have Exchange 2007 SP1 Update 7 running on a Windows 2003 SP2 single box. It is behind ISA 2006 firewall.
Twice now different people have said that they are getting a 5.5.0 NDR when trying to send to us. It appears to be intermitant. The diagnositic code is:
Diagnostic-Code: smtp; 354 Start mail input; end with <CRLF>.<CRLF>
I have tried looking up the error codes and they haven't told me anything specific. I have telneted to test it out and my email gets through every time. However I do get a weird response after typing DATA -
220 <myEmailServer> Microsoft ESMTP MAIL Service ready at Tue, 31 Mar 2009 17:09:42 +1300
250-<myEmailServer> Hello [XX.XX.XX.XX]
250-AUTH NTLM LOGIN
250-X-EXPS GSSAPI NTLM
250 2.1.0 Sender OK
250 2.1.5 Recipient OK
354 Ready, steady, go
Why is my Exchange server responding with Ready, Steady, Go? This can't be normal?! Could this be why some people are getting the 5.5.0 354 error?
