Custom rules for spamassasin?

[Andy Pieters]

Hi List

We are getting quite some spam from japan and spamassassin doesn't consider it 
as spam.

Apart from selecting each of such message as spam, is there a way to add a 
rule, or does anyone know about which rule to activate?

The messages have almost always the same structure:

Received: from vlaamse-kern.com (pl027.nas934.d-osaka.nttpc.ne.jp 
[61.197.82.27])
	by giga.vlaamse-kern.com (8.13.1/8.13.1) with SMTP id jADFi1Wo028374
	for andy at vlaamse-kern.com; Sun, 13 Nov 2005 16:44:02 +0100

Note that OUR domain is vlaamse-kern.com and that the sender pretends to be 
vlaamse-kern.com as well!

Furthermore, they always come from japan

And lastly

From: =?iso-2022-jp?B?QVRTVVNISQ==?=<atsushi37ry4wh at hotmail.com>

From pretends to be from hotmail.

I know of the test FORGED_HOTMAIL_RCVD2 but I have seen this one being 
triggered on valid hotmail messages as well.


With kind regards


Andy
