Hmmm ... they obviously don't like you for some reason:

1027 [root:tru.leerlingen] /root # telnet 65.24.7.64 25
Trying 65.24.7.64...
Connected to clmboh-mx-10.mgw.rr.com (65.24.7.64).
Escape character is '^]'.

FWIW this site has a CIDR REJECT block on 65.24.0.0/14 (Road Runner
HoldCo LLC) and turns away tons of spam, but they still like us :)
