Comment sorbs is one the best blacklists out there (Score 3, Informative) 226
I work at the abuse dept. of a large dutch ISP and we rely heavily on sorbs. When I started working there one of my collegues convinced us that there is no way you could be able to contact sorbs and I thought that to be true. We found out however that it is really not that hard to get in touch with them and if you follow their guidlines, you never have to pay for delisting. The paying part is mainly to scare of spammers delisting adresses they do not own. They use a smal set of totaly acceptable rules to delist adresses from their DUL list (if u use a mailserver on a dynamic adres, go get a static one. If you can't, you should be using your ISP's mailserver). Their rules:
1. Only the owner of the adress space may contact them, as listed in one of the five RIR databases (RIPE, ARIN etc). We always use abuse@isp.com, because this is a known adress in RIPE.
2. The IP adress must be known as static and have a PTR-record stating it is static (mail.domain.com is acceptable).
3. It must have a correct A-record.
4. The TTL in of the A-record must be 86400 sec.
If you contact them in the way they wish to be contacted (just read their website, it's not that hard), they will delist you in 24-48 hours. However, if you aren't the owner of the adress space or the simple rules are not followed, your request wil be ignored. Everyone who thinks they can't get through to sorbs just isn't reading their guidelines, it's that simple.
