Hey, you're not the only one having to deal with this. About 2 years ago I
had a client who was hosting about 500 web sites at that time and some idiot
on the same class C sent some spam out and the entire class C was blocked.
I've even had AOL block my client's server because one of his clients sent
out some spam. So AOL proceeded to block the entire server for about 800
email addresses.
Any kind of IP based blacklisting, regardless of if it blocks a class C or a
single IP address has the potential to cause false-positives. And
unfortunately, unless you're dealing with a company like AOL that you can
call on the phone and plead your case to you will probably be on that
blacklist until the ones who maintain it take you off.
I've had plenty of clients complain about the type of blocking that you're
describing and for all the research I've done (and I've done a lot) the only
way to get off of a majority of the RBLs is to wait.
