One caveat on that would be what happened to earthlink and probably a few
others a little while back. I read an article that the SoBig/Blaster and other
viruses happened to knock out the set of RBLs that earthlink happened to be
using. So earthlink starting rejecting perfectly valid email because their MTA
or SMTP proxies, or whatever, could not connect to the RBLs. Perhaps that was
just some erroneous assumptions going on there, as in: if you don't receive an
answer from the RBL then assume it's spam.
