Since yesterday the blocklist of SORBS is used on
servers to block open proxies.
SORBS is for email proxies, isn't it?
What's the advantage of blocking open email proxies from using
SORBS also maintains a list of open web proxies.. since web based
spamming has become a large issue as well.. (think blogs and wikis)
The FAQ URL that someone cited seems to demonstrate a technique that can
be used by a spammer to use an open http proxy to get trusted access to an
email server on the same system, bypassing the relay rules and
compromising the mail server. This is pretty serious stuff. Web proxies
*should not* be open.
