Road Runner utilizes a volume based spam block from my understanding. If you send over X amount of email in Y amount of time, they block you. You need to create a rule that staggers the number of messages you send to all rr.com domains so as to not trigger the threshold and become blocked. See here for the limits: http://security.rr.com/spam.htm#ratelimit

So they'll block all the major ISPs smtp relays, but not the infected PCs used to inject spam? Smart. Do their customers really accept this? Bjørn _______________________________________________ NANOG mailing list NANOG@nanog.org http://mailman.nanog.org/mailman/listinfo/nanog

Honestly I doubt we are blasting Road Runner that hard. When I look thru the log files it really does not look that bad except for on the 19th. So I would have to say this is not how they have chosen to block me. Clinton Popovich Systems Administrator Consolidated Communications, Inc.

I have about 50,000 customers sitting behind this old mail server currently. I have emailed back in forth with someone from roadrunner and when he sends me back the spam example it is always from the 19th. So far from the spam sent out on that day we have been blocked 5 times. Does anyone have a contact for Road Runner that I might be able to have.
