Right now the SMTP DNS Adress field is set to 63.85.233.135. Originally it was set to "63.85.233.135 63.85.233.136" (without quotes of course). As per you last suggestion I removed the second address. The system TCPIP settings are currently pointing to those same two addresses as primary and secondary respectively. Here are the super debugging results from the time I restarted SMTP until the message is requeued. Although I was trying to keep the destination domain anonymous, I'll go ahead and leave it in the logs since that may be required to properly trobleshoot this. My machine is sdumax.
