Problem: Certain outgoing mail sits in the queue of the SMTP virtual server until it times out. Errors in the event log report: Event ID 4000 Message delivery to the remote domain 'domainname.com' failed for the following reason: The remote server did not respond to a connection attempt.
Setup: Exchange 2000 SP1 Windows 2000 Server SP2 AD integrated DDNS No DNS errors or problems in event log No other errors in the event log other than the one mentioned above No problems with incoming mail or internal mail No AV software (yet) Resources checked: The usual exchange haunts of swinc and swink, and the MSKB where I found: Q280794 XIMS: Message Cannot Be Sent to Domains with MX Record Pointing to CNAME Record Q288718 XIMS: Message Cannot Be Sent to Domains with MX Record That Points to IP Address Both of which indicate a service pack fix - also the file versions I have are newer the versions mentioned in these articles Any help would be appreciated, Tony List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
