Have you checked to see if you appear on any ORBZ type blacklists? Eric
-----Original Message----- From: Scott Force [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 25, 2003 11:30 AM To: Exchange Discussions Subject: SMTP Woes Exchange 5.5/4/Win2000/4. About 1 week ago I started having problems e-mailing users @verizon.net (206.46.170.12). The NDR's state "One or more mandatory argument(s) were missing from the recipient" and the stuck messages in the outbound IMS queue have the follwing error "[450 Requested mail action not taken-Try later:sc006pub.verizon.net]". This is the only domain I am having problems e-mailing. I am not on any RBL's and I can telnet their relay server for about 10 seconds then it disconnects me. I've had the Verizon users contact support and they are telling them it's a problem on my end. What should I be looking at? Thanks, Scott. _________________________________________________________________ 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]
