I think that depends on the response code that your server receives from the target SMTP server. It could be misleading your server into thinking that it can try again. I think I have seen something like this happen in the past.
Also, have you checked the remote domain's MX records and tried to telnet on port 25 to those MXes? Maybe they did something (like screw up their MX records for example) and the MXed IP address cannot be reached? Or it can be reached but does not open a connection on port 25? You server knows that MX record for that domain exists and is pointing there and that's why it keeps the message in the retry queue, just can't successfully connect and hand the message over. Have you checked your SMTP logs?

If there is a "restriction" on the remote server, it shouldnt be sitting in the IMS anyway, it should simply bounce back to the sender almost immediately after the remote server denies the connection. -----Original Message----- From: Scott Force [mailto:[EMAIL PROTECTED] Sent: Friday, December 19, 2003 10:21 AM To: Exchange Discussions Subject: Header Info Exchange 5.5/4 Win2000/4 Potentially silly question. (Technical, non-ethical, sorry) If I send an e-mail to external domain and it sits in my outbound IMS queue and can't get delivered because of a restriction on the receiving domain's e-mail server, my NDR should have header info in right? _________________________________________________________________ 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] _________________________________________________________________ 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]
