Hi , anyone knows this rbl ?
http://v4bl.org/about.html
...
A very extensive list of IPs; which include:
» Well known spammer IPs
» UBE/UCE abusive IPs
» rfc-ignorant IPs
» IPs with mismatched DNS and RDNS (FCrDNS failure)
» IPs with mismatched rDNS and EHLO/HELO (FCrDNS failure)
» IPs of SPAM friendly ESP/HSP/ISP
» Obfuscated intermediaries / Alias domains / Disposable domains /
Email-only domains
» Intermediaries without easily accessible contact information
» botnet IPs
» and much, much, more...
...
sounds very strange to me, this might result in massive problems at some
sites, in special checking EHLO/HELO missmatch
Best Regards
MfG Robert Schetterer
