QUESTION POSED ON: 18 January 2006
I'm running Exchange 5.5, and a certain host (EXTRANET2) needs to send mail out via SMTP. My IMC/SMTP servers are HOCON01 and ZABRYH02. Both are configured to allow SMTP connections from EXTRANET2.
When testing for connectivity, I start a telnet session from EXTRANET2 to HOCON01 on port 25, and instead of receiving the usual greeting as expected:
220 zabryh02.medscheme.com ESMTP Server (Microsoft Exchange Internet Mail Service 5.5.2657.72)
I get an apparently malformed greeting message:
220 *****0**********************************************************************
*****2*************
It seems like the connection is made, since it was not rejected, but no SMTP functionality is available. It does the same thing whether I'm connecting to HOCON01 or ZABRYH01. Other hosts can connect to HOCON01 and ZABRYH02 successfully.
EXTRANET2 is running Windows 2003 Enterprise Edition SP1 and HOCON01 and ZABRYH02 Windows 2000 Standard Edition SP4.
Do you have any ideas?
