It might be something on the other end. 4.4.1 usally indicates a network issue. Does it happen for all email sent to those two domains. How was it sent. Anything in the Event logs?
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sean Winters Sent: Sunday, September 28, 2003 5:47 PM To: Exchange Discussions I am working with a relatively new Ex2K build and have had two different external contacts report intermittent NDR's. There is no PIX firewall in place and ESMTP verbs have been disabled on our end. The NDR is "4.4.1 Did not receive the expected protocol response." Searching the usual sources has turned up nothing. Any ideas/suggestions? _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang =english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
