[Dovecot] compilation and installation of dspam-plugin

[Stefan Schmidt]

hello johannes,

i just discovered your wonderful plugin for dovecot. it was pretty much
exactly what i was looking for, only that i didn't know that yet :)

"Instead of moving mail into special folders, the user has two actions
available: moving it out of the SPAM folder and moving it into the SPAM
folder. The dovecot plugin watches these actions [...] and tells dspam
that it made an error and needs to re-classify the message, depending on
the action the user took. The user can now move the message directly
into whatever folder she choses, and it all works. [...]"

i think this is the most usable and intuitive approach to dspam-training
i have seen so far and would love to integrate dspam with this plugin
into my current setup (postfix + maildrop + dovecot). i have installed
dovecot via package from the debian stable section [1] therefore i am
currently using version 0.99.14 in my setup. despite this difference in
version i gave your betacode [2] a try together with the source of the
corresponding dovecot-version [3], hoping it wouldn't crash and burn
when used with my earlier version of dovecot. but i didn't get to the
point where i could actually testdrive it. i tried compiling the plugin
with the instructions contained in the file, but the compilation didn't
suceed.
