XFOR: IMC Does Not Check Hosts Table If DNS Server Down

SYMPTOMS

When you have a DNS server defined on the Exchange NT server and have the Internet Mail Connector (IMC) configured to "Use DNS," outgoing messages will not be delivered if the DNS is unavailable.

If the DNS server identified is unavailable, the IMC will NOT look to the Host file for another available DNS. It will place the outgoing message in the Imcdata\out directory for future delivery.
