Thanks for all your feedback, I am pretty sure the DNS settings are correct. I have checked them and there's nothing amiss there.
The SMTP connectors both point to the same smart host (firewall) for traffic. The e2k SP2 option looks tempting and adds a 4th option to the possible fixes: 1. re-create the e2k SMTP connector and hope that the problematic e2k server sees it. 2. apply E2k SP2 to both the e2k servers 3. upgrade the e5.5 server to e2k and then remove the "IMC", followed by removing the server from the org. 4. call PSS Thanks for all of you help thus far. For a little while there... I thought I was going nuts...

Since you've done everything else, have you checked your DNS setup ? Specifically, what are the entries for your preferred DNS servers ? What entries do you have for forwarders ? Are you forwarding to an ISP or other internet DNS service ? _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
