Running a private mail service for family & friends through an rr.com
dynamic IP, I have three things to say:

 1) Please dont block my mail :(
 2) rr.com *does* scan their customers. They scan about seven different
ports, and if they find an SMTP listener they will open-relay test it with
several messages. Once a week my periodic mails show their failed
attempts to relay through me. I assume they test the other ports similarly
if they're found to be open (CONNECT attempts on 8080, for instance).
 3) I much prefer this to any sort of inbound port blocking.

And, not that I want one, but how did you guys get rr.com e-mail
addresses? Twice the only thing the cable guy has done is leave me a modem
when left me the cable box, and twice I have connected it myself, never
hearing from them again.
