[NANOG] Block: Road Runner Internal IP blacklist

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

Here's a link to get unblocked: http://security.rr.com/mail_blocks.htm

Good luck.

Subject: [NANOG] Block: Road Runner Internal IP blacklist

Greetings all,  I am having a bit of trouble with Road Runner, we have been
blocked repeatedly for email that I believe to have been sent out on the
19th.  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.
