We (Atlantic.Net) have gotten a flurry of abuse complaints from people who's systems have been scanned by 209.208.0.15 (rt.njabl.org...a DNSBL hosted on our network). I'm hoping the new PTR record will head off many complaints now. For the past 15 months, NJABL has reactively tested systems that have connected to participating SMTP servers to see if those systems are open relays. Just over a week ago, NJABL added open proxy testing to its relay testing software. The proxy testing checks for a variety of common proxy software/protocols on about 20 different ports simultaneously. This is apparently setting off some IDS/firewall alarms. We do not consider what NJABL does abuse, and we reply to all the complaints explaining that the complainant should go have a look at http://njabl.org/ and hopefully they'll understand why their system was scanned. This sort of activity is becoming more common / mainstream, so people ought to just get used to it. Road Runner is doing the same thing (according to http://sec.rr.com/probing.htm) which is pretty ironic given how their security department has gotten along with (or not) various DNSBLs in the past. BTW...in the week that NJABL has been testing for open proxies, more than 18000 have been detected, pretty much all of which are actively being abused by spammers, else mail would not have come through them. ---------------------------------------------------------------------- Jon Lewis *jlewis@lewis.org*| I route System Administrator | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
