> The sequence that IMail uses to resolve/deliver mail is:
> a. check for the host in IMail registry
> b. check for the host alias in IMail registry
> c. check for the host in "WINNT\...\etc\hosts"
> d. perform an MX lookup for the host on the DNS server defined in Control
> Panel -> IMail -> SMTP -> Domain name server
> e. perform an A lookup (for the MX record above) on the DNS server defined
> in Control Panel -> IMail -> SMTP -> Domain name server
> e1. if a CNAME came back on e., then goes back to d. with the new response
> f. asks the NT network stack for an A lookup of the domain name
> g. prints "stack connect fail" on name
>
> The routine above returns at any point in the sequence if a correct answer
