I went to study some long and I developed a small program, herebelow.
But I'd appreciate if it vill come some suggestion for a pythonic cosmetic
fashion :)

Thank to everybody.

Also the config File enclosed (some detail is obscured for obvious purposes).

[Filters]
# A = Allow (anything which starts with "a" is filtered as allowed)
# to keep as good.

A01 = ^From: .*\.cz

A04 = ^(To|Cc): .*fglkfrtrtthajl@

A06 = ^From: .*\.my

# D = Deny (anything which starts with "a" is filtered as denied) and will
# fill the list for deletion.

D01 = ^From: .*\.com\.my
D02 = \*\*\*SPAM\*\*\*
==========================================================================

Let me say that is an experimental program for learning purpose, yet. More
things should be implemented like :
1 Real deletion for those email listed in the report file.
2 a single group pattern for the regex search
3 Logging errors and all functions mentioned in the "Setting" section.
4 last but not least a GUI.

The idea was born when i was looking for the "mailfilter" package for Arch
Linux. Actually has been retired. Then I tought " It would be good if a
platform indipendent program will do the same job or a bit more".

Testing on win32 platform is good help.
So, if somebody like to join, very welcome for all of the possible chances,
please try to contact me at _fulvio AT tm DOT net DOT my_.
