If I do this it seems to work, however, as the same error message "501 Syntactically invalid EHLO argument(s)" is being generated by exchange, does this mean that for some reason Exchange 2000 isn't following the RFC? -----Original Message----- From: Wall, Murray TMC [mailto:[EMAIL PROTECTED]] Sent: 05 June 2002 14:03 To: MS-Exchange Admin Issues Subject: RE: SMTP Protocol Error Make sure to follow the rfc... RFC 821 August 1982 Simple Mail Transfer Protocol 3.5. OPENING AND CLOSING At the time the transmission channel is opened there is an exchange to ensure that the hosts are communicating with the hosts they think they are. The following two commands are used in transmission channel opening and closing: HELO <SP> <domain> <CRLF> QUIT <CRLF> In the HELO command the host sending the command identifies itself; the command may be interpreted as saying "Hello, I am <domain>". -----Original Message----- From: Stuart Pittwood [mailto:[EMAIL PROTECTED]] Sent: Wednesday, June 05, 2002 7:02 AM To: MS-Exchange Admin Issues Subject: RE: SMTP Protocol Error Ricki, If I telnet into the offending mail server, I get the SMTP Banner (after a very long wait) If I try either EHLO or HELO I get the error the following error 220 ultra19.uk2net.com ESMTP UK2.NET - UK's Biggest Host Wed, 05 Jun 2002 13:52 :04 +0100 501 Syntactically invalid HELO argument(s) 501 Syntactically invalid EHLO argument(s) This happens on either of the listed mail exchangers Thanks Stu -----Original Message----- From: Rickenbacher Beat [mailto:[EMAIL PROTECTED]] Sent: 05 June 2002 12:59 To: MS-Exchange Admin Issues Subject: AW: SMTP Protocol Error What if you're manually sending a mail from E2K server (telnetting port 25)? Is there a second mail server showing up in nslookup? Using this one (via telnet and/or connector/smarthost) is also not working? You also can try to change the internet message settings for that domain... And then you can create a connector for this domain and change the default settings (helo instead of ehlo etc.) Ricki -----Ursprüngliche Nachricht----- Von: Stuart Pittwood [mailto:[EMAIL PROTECTED]] Gesendet: Mittwoch, 5.

When sending to a particular destination the queue is holding the message with the following error, SMTP Protocol error occured. I can however, send mail to this domain from another account (hotmail etc). At first I thought it could be because our service provider had neglected to add a PTR record for our mail server. Thi has now been corrected but the problem still persists. We are running WIn2K SP2, Exchange 2000 SP2 with the admin patch and the new smtp patch. Can anyone tell me what causes this? or is it exchange saying "i really don't know why I can't send this" How can I troubleshoot this? any advice appreciated.
