I agree. Some of the lookup errors are expected. They are the result of
attempts to translate names like fasteagle to and ip address. What is not
clear is why the lookup for smtp.roadrunner.com is failing.

One thing I do notice is that

dnslookup -type=mx smtp.roadrunner.com

and

dnslookup -type=mx roadrunner.com

produce different results and the later looks more correct. That said

telnet -p 25 smtp.roadrunner.com

gets me to the mail server.

>> --parseaddr(listsns@roadrunner.com)
>> map_lookup(host, roadrunner.com) => host_map_lookup(roadrunner.com) => FAIL (2)

>I don't know what the FAIL(2) means but I do not get those errors.

I think the is the result of looking for builting mapping tables, which
probably don't exist. Error 2 would be file not found.

>> remotename => `s-geo@usa.net'
>> getmxrr: res_search(mail.adelphia.net) failed (sock_errno=10060, h_errno=2)

This is the expect error given what is happening.

#define SOCETIMEDOUT (SOCBASEERR+60) /* Operation
timed out */

You can find these in nerror.h in your programming toolkit.

>The "sock_errno=10060, h_errno=2" seems to me to be a DNS request that

It could be. The error is generic. It occurs anytime the socket open
times out.
