there is a chch produced commercial package for windows that downloads
the mail headers from a pop box. you then scan for spam (most of it is
prettty obvious from the subject and sender) and kill them on the server
without ever downloading the whole message. no doubt time consuming. no
doubt realtively trivial to write a linux equivalent script if you
understand the pop protocol (relativley simple) and are competent in
scripting (ie not me). In fact someone has probably done it.
:-) MailWasher (http://www.mailwasher.net) from Firetrust (www.firetrust..com).
It does indeed do generally what you say, and will combine a number of techniques (white/black-listing, etc), as well as let you bounce errors back again, to make it look like the email address spammed was invalid.
It will run in an advertised-sponsored mode, and can be registered too (of course)

Q.������� Does it run under Linux?
A.������� While there is not a native Linux version of MailWasher available, there is a codeweavers WINE port for Linux available.
Head to http://appdb.codeweavers.com/ and search for Mailwasher.

From: Julian Visch [mailto:[EMAIL PROTECTED]
I am trying to block spam so that I don't have to download the whole spam
first, is there any tool to do that?
It depends on how you're willing to collect your email. If you just want to carry on using an ordinary mail client to collect mail from your ISP with POP, then your options are limited to programs that download _some_ of the message.
For some reason, these programs aren't well-popularised under Linux, although they're common for Windows users. I had a look at SourceForge and searched for "spam pop" and found a few client programs mentioned ...

http://eremove.sf.net/ (more limited)
There are a multitude of solutions available for you if you run your own mail server, or have access to the mail server that receives your mail before you download it with POP ... but that doesn't seem to fit your situation ...
