About 33% of non-tagged SPAM I find in my mailbox currently looks like:

Content-Type: multipart/alternative;
The first part is: text/plain and contains random words
The second part is: text/html and contains the "real" spam.
Well, I do see the gibberish only ... .

Also: Most often the Subject line is contained of random words, too; and
X-Mailer as well.

Can you configure SpamAssassine to take into account the MIME-structure
when trying to identify the text/plain portion as "gibberish"?

Perhaps, would it make sense to do some sort of compare between both
portions? E.g. all words from the plain/text part must be in the text/html
part, too? When someone builts a HTML mail and when the text/html part is
generated by the Mailer, I guess, it works straight forward and it will
just remove the tags, hence, the words of the plain/text part should even
be in the same sequence as those of the text/html part?
