I have an issue with an Exchange 2000 SP3 server where an email sent from inside the Exchange organization is not getting to some recipients in a specific domain. I have logging turned up, and found a strange message:
550+not+local+host+recipientdomain.com,+not+a+gateway The 550 error maps to a generic protocol error (SMTP error), but I can't make heads or tails out of the rest of the message. What is strange is that the domain comes up successfully in nslookup and from the Exchange server, I can connect via telnet to port 25. The users have had no trouble sending email to this recipient at this domain before or since, except for this most important email (or course). There was no NDR, no nothin' - just seems like the email went into a black hole. Thanks for any assistance! _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
