Don't count on it.
Here's what happens.
1) The blacklist folks set up an e-mail address on the internet. They
call it a SpamTrap or sometimes this technique is called a
"honeypot". The idea is to set up something attractive to the flies
(eg spammers)
2) They intercept the spam they receive, and then work backwards to
figure out which parts of the internet it came from. They find the
addresses of the mail servers that originated spam.
3) They create a list these "spam" e-mail address servers, with the
implication to other ISPs that people can simply reject all main from
these servers - and voila, no spam.
However, this scheme doesn't work, everyone knows it doesn't work,
and yet they continue to perpetrate it.
The problem appears in step 2. The assumption is made that any ISP
that is e-mailing spam must be complicit with the spammer. These
days, most spammers use a "bot" network of compromised computers that
they control remotely. Someone puts an unprotected computer out
there, the spammers install their remote control software, and they
have it send the spam. Most of these computers become "owned" by the
spammers due to sheer ignorance of the people setting them up.
It's not surprising that a large ISP like Comcast or BellSouth gets
blacklisted with great regularity, because it is very easy for
someone to be careless when setting up a computer. That's why the
blacklist guys should just clear their lists.
Blacklisting is a dumb idea. It does nothing to the spammers and only
hurts legitimate internet users. I hope one day, one of them gets
sued for unfair restraint of trade for blocking e-mails and loses big
time. Maybe that will put an end to that nonsense. (Of course, I hope
the same fate awaits the spammers, too)
