I use Untangle and love it, but It is a full network solution not an individual account method of combating spam, but it is at least free. Good luck

I've been getting bombarded with spam recently from a particular source. (15 of the bloody things during my lunch break alone.) Hawking a wide range of things, the URLs in each of the spams look something like this: http://somedomain.com/bYxbyYbEQxQExyMyEyEIMxobFdYQy Currently my Postfix setup is using greylisting and the zen.spamhaus.org RBL. The spammer is jumping around various IP addresses faster than zen.spamhaus.org can list them. The URLs being used change constantly and he's using an email server that retries messages so greylisting isn't blocking them. I've tried adding the RBL 0spam.fusionzero.com to my config. This RBL blocks entire C blocks of IP addresses since this spammer appears to be purchasing a C block and working his way through the entire range as each IP becomes listed. The problem with 0spam.fusionzero.com is that it's a bit TOO aggressive and sites like hotmail.com and ConstantContact.com are getting caught up in that RBL. So, any suggestions of other RBLs that aren't quite so aggressive or does anybody have another method of fighting this particular brand of SPAM?
