Interesting RoadRunner Policy

We recently noticed (among the hundred or so machines that scan us every day) some constant scans from the same machine, securityscan.sec.rr.com. When we contacted the folks at RoadRunner we received the attached response. I am not exactly sure what to think. I certainly hope these scans do not become standard ISP practices. Anyhow, I just thought I'd share it with all of you guys. Alex PS - Interestingly enough, they were hitting several different ports on our boxes, all expect port 25. ------- J.

We fully understand your concerns surrounding the probing of your machine. This issue has been raised internally and we hope this email helps you better understand our process. The intention of this process is truly not meant to be a "big brother" system, but we understand that some may view it as such. Our ultimate goal, however, is to protect our network, our customers, and our role accounts. Road Runner has begin the REACTIVE testing of IP addresses which connect to its inbound SMTP gateways. If your machine connects to ours to send email, we reserve the absolute right to perform SMTP relay and open proxy server tests upon the connecting IP address to ensure that the machine at that IP address cannot be abused for malicious purposes. These scans are done once per day per IP, via an automated process, and only on those servers that have sent our subscriber base mail. The only way for these tests to occur is if an IP address connects to our inbound SMTP gateway. If found to be an open proxy or smtp relay, the IP address will be blocked at our mail gateway borders with one of the following error messages: ERROR:5.7.1:550 Mail Refused - See http://security.rr.com/mail_blocks.htm#proxy ERROR:5.7.1:550 Mail Refused - See http://security.rr.com/mail_blocks.htm#relay We understand that some entities may not wish to be scanned as part of this automated process. If you do not wish to be tested by Road Runner, there are two ways to accomplish this: 1. Send an e-mail to 'donottest () security rr com' with the IP address that you do not wish to be tested. Please note that if you are not the designated contact for your IP address range (for example, if you are on a cable modem, DSL, or dialup range), we will be unable to fulfill your request for addition or removal. 2. Do not connect to our inbound SMTP servers. Again, this test is only conducted on servers that connect to our servers. If you have any further questions, you can visit http://security.rr.com or contact Road Runner Security via e-mail at 'spamblock () security rr com' Regards, Road Runner Security ********** Participation and subscription information for this EDUCAUSE Discussion Group discussion list can be found at http://www.educause.edu/memdir/cg/.
