Ist v4bl.org sicher?

Those are lamers, they don't know what they talk about, and wonder if they already red an RFC. They blacklist your IP without a real reliable reason. And so they trust an anonymous that will tell them that they must blacklist an IP, but they refuse to remove the IP from blacklist if this is ask by the real owner... There is a big issue here. Also they are several topics about this really bad company: ***** ***** http://www.webutation24.org/go/review/v4bl.org

They list IP for not only spam but also rDNS issues and hardly ever delist any IP. You can't get out of this list. They will find any reason to not delist you - reasons not related to email or spam (anything "suspicious" or "not right" in their eyes about your domain name or website suffices - you get "SITE" problem). So they have huge number of false positives. We got one of our VPS servers listed because of temporal reverse dns problem because of misconfiguration that was there for few days and can't delist since then. So use this list only if you want block some spam and some good emails too.

Before using this kind of list for your mail server you should be aware of the following thread: ***** (IMHO - serious mail providers should be carefull with that list, to avoid stress conditions with their customers) To verify a difference you may want to try *****

This site list negative IPs they have one time create spam and they dont delist automaticly when this IPs never been send spam again. As a new owner of new IP-Blocks many many many IPs was listet black, but we have never send spam - the old owner of this IP-block possible years ago has send spam! Yes when a client has bad software, can been an intruder create spam. When we see this, we block this directly, thats a normal Hosting-Work. The delisting posibilities on this site not work and their administrators blocks too IPs they was not listet before without that was sending spam from this IPs - in beetween of the delisting process of other IPs! You can find too many sites, they write that their positive fault rate is very high and on their own statistic site, you find positive fault rates of more as 25 % - So this is a site and a service never can been used and we are the meaning, thats absolut ilegal, what they doe! So when you have same problems about this list, please make a claimb too the w3c and RIPE - We have do this today! You find the address in the whois - is a USA-contact and w3c works here very fine! It can not been, that companies are compromised with wrong black listing only why they can not refresh their databases! And they will sell a paid service, can been to get money with this ilegal black listing! Regards ***** - Internet-Service-Provider Detlef Bracker

RBL which would be good, except that's it's relatively unknown and relies completely on IP owners knowing they exist and checking the owners' IP address against the RBLs list to find out if an IP is listed. Once removal request is made, the vendor says to expect 72 hour removal, but in practice it's in excess of 96 hours and still counting. As such, IP list is outdated and unreliable. List should auto unlist an IP after 72-96 hours of no SPAM activity being recorded. Manual intervention, as stated above, is unreliable at best and irresponsible at worst.
