Hi All,

I run mailman on Ubuntu 14.04 with Postfix.

It has been setup from the Ubuntu packages.

The problem I have is there is there are a large amount of spam coming
through, which spamassassin does not seem to be giving a high enough
score and discarding.

I run the mmlearn script
(http://www.jamesh.id.au/articles/mailman-spamassassin/mmlearn), which
processes a very heavily spammed list.

Learned tokens from 289 message(s) (1028 message(s) examined)

The problem is, "teaching" spamd, seems to have no results.

Here are some example spam messages, where spamd just seems to setting
the score too low.

X-Spam-Status: No, score=-0.3 required=5.0 tests=BAYES_00,
HTML_FONT_LOW_CONTRAST,HTML_MESSAGE,HTML_TAG_BALANCE_HEAD,RDNS_NONE,
