Кто-нибудь использует блэклист SORBS? Не сильно они там палку перегинают?
На сайте список, с чего почта блокируется, достаточно внушительный...
dnsbl.sorbs.net - Aggregate zone (contains all DNS zones)
http.dnsbl.sorbs.net - List of Open HTTP Proxy Servers.
socks.dnsbl.sorbs.net - List of Open SOCKS Proxy Servers.
misc.dnsbl.sorbs.net - List of open Proxy Servers not listed in
the SOCKS or HTTP lists.
smtp.dnsbl.sorbs.net - List of Open SMTP relay servers.
web.dnsbl.sorbs.net - List of web (WWW) server which have spammer
abused vulnerabilities (e.g. FormMail scripts)
spam.dnsbl.sorbs.net - List of hosts that have been noted as sending
spam/UCE/UBE to the admins of SORBS. This
zone also contains netblocks of spam supporting
service providers, this could be for providing
websites, DNS or drop boxes for a spammer. Spam
supporters are added on a 'third strike and you are
out' basis, where the third spam will cause the
supporter to be blocked.
block.dnsbl.sorbs.net - List of hosts demanding they are never tested by
SORBS.
zombie.dnsbl.sorbs.net - List of networks hijacked from their original
owners. Some already used for spamming.
dul.dnsbl.sorbs.net - Dynamic IP Address ranges (NOT a Dial Up list!)
rhsbl.sorbs.net - Aggregate zone (contains all RHS zones)
badconf.rhsbl.sorbs.net - List of domain names where the A or MX
records point to bad address space.
nomail.rhsbl.sorbs.net - List of domain names where the owners have
indicated no mail should ever be sent with these
domains.
Вообще, было бы интересно узнать, какие dnsbl народ использует.
