[Dovecot] dspam integration

[Eugene Prokopiev]

Hi,

I see http://johannes.sipsolutions.net/Projects/dovecot-antispam and
http://blog.cynapses.org/2007/09/13/dovecot-dspam-plugin/ solutions.
Second git repo is not answer, first one is cloned, but I see some
drawbacks with it.

Dspam backend is more native solution but libdspam using instead of
dspam external binary looks like preffered way to integrate dspam.
Another problem is waiting for dspam child process exit, so IMAP
session is blocked. Why not to fork and forget dspam child process?

Email sender backend is non-blocking, but using MTA is great overhead.
Calling external program with some args and mail body via pipe can be
more suitable way, so external program may be dspam binary directly or
shell/perl/python filter to any antispam engine via sendmail or
something else.

Has anybody plans to implement this features or it will be better to
try it myself?
