- Yes, Julie, this a fact of life nowadays! Spamhaus is an online
service that maintains a record of mail servers that send out
lots of spam. Administrators of other mail servers can then
tell their servers to check with Spamhaus before accepting
delivery of a message, and reject any messages coming from the
identified spammer servers. "RBL" stands for Real-time Block
List, (or Black List), meaning the block list is dynamic and
constantly changing as new info comes in.
I work at the University of Pittsburgh, and very often AOL blocks
mail from Pitt because too much spam was coming from Pitt servers
the previous couple of days. With a university this big, there
are bound to be some computers that haven't been properly
safeguarded, and get hacked into and turned into zombies, sending
out tons and tons of spam on behalf of a spammer who is probably
halfway around the world.
There's not much you can do, unfortunately. Your ISP could put
Yahoo mail on a "white list" that would exempt it from any spam
filtering, but it's unlikely they'd ever agree to do that. Yahoo
has to figure out a way to keep people from exploiting it for
