There is nothing wrong with the connection to sendmail at your site.

[egreshko@misty egreshko]$ telnet 24.24.15.155 25
Trying 24.24.15.155...
Connected to syr-24-24-15-155.twcny.rr.com (24.24.15.155).

The problem is still in DNS....

[egreshko@misty egreshko]$ host -t mx mccorduck.ws
;; connection timed out; no servers could be reached

A quick nmap scan of your host shows....

Which indicates that port 53 for your DNS server is not opened.
