Hi all, I am having trouble sending to a specific (external) domain, and am trying to work out what is happening. My users will send an email, but the email will never seem to get out of the smtp queue. When I look at the SMTP logs, I can see the following: OutboundConnectionResponse SMTPSVC1 EXCHANGE - 25 - - 220+mail.yourcompany.com+ESMTP+Service+ready 0 0 40 0 172 SMTP OutboundConnectionCommand SMTPSVC1 EXCHANGE - 25 EHLO - EXCHANGE.myccompany.com 0 0 4 0 172 SMTP OutboundConnectionResponse SMTPSVC1 EXCHANGE - 25 - - 502+Command+not+implemented 0 0 27 0 235 SMTP OutboundConnectionCommand SMTPSVC1 EXCHANGE - 25 HELO - EXCHANGE.mycompany.com 0 0 4 0 235 SMTP OutboundConnectionResponse SMTPSVC1 EXCHANGE - 25 - - 250+Requested+mail+action+okay,+completed 0 0 41 0 329 SMTP OutboundConnectionCommand SMTPSVC1 EXCHANGE - 25 MAIL - FROM: 0 0 4 0 344 SMTP OutboundConnectionResponse SMTPSVC1 EXCHANGE - 25 - - 250+Requested+mail+action+okay,+completed 0 0 41 0 407 SMTP OutboundConnectionCommand SMTPSVC1 EXCHANGE - 25 RCPT - TO: 0 0 4 0 407 SMTP I am not sure why this is happening, and whether or not the trouble is originating at our end? Thanks for any advice... David
