It's just as I suspected, they must have outgoing traffic on port 25 
blocked.

I can ping fine, I can telnet to port 80 or 110 on other machines, 
including the ones in question, I just cannot telnet to 25 on *any* 
machine including mail.neilschelly.com.

Thanks to all for the help, I'll take it up with GoDaddy.
