If I may make an analogy, if the OP had asked someone to teach him how
to swim then Mr. Witten's answer, although accurate, somewhat resembles
throwing the questioner from the ten metre board over the diving pool.

Stanislav: can you tell us how familiar you are with the structure of

(1) emails in general and

(2) MIME-structured emails in particular?

It's especially important to know what you're dealing with before you
try to filter mail because otherwise the results may be disappointing.
