[GRASS5] Spamfilter added for RT Bugtracker mails

[Markus Neteler]

To get rid (hopefully) of most spams arriving in 'grass5'
mailing list via bugtracker, I have added a filter rule
to pipe RT mails through 'bogofilter':

 Reply-To: guest user via RT <grass-bugs at intevation.de>
 From: guest user via RT <grass-bugs at intevation.de>
 To:
 Cc: grass5 at grass.itc.it
 X-Request-ID: 2174
 X-RT-Loop-Prevention: bug
 X-Sender: guest
 X-Managed-By: Request Tracker 1.0.7 (http://www.fsck.com/projects/rt)
 X-Bogosity: No, tests=bogofilter, spamicity=0.000000, version=0.15.13.1
   -> this line was added

 Subject: [GRASS5] [bug #2174] (grass) Mac OSX startup: ERROR: Invalid return code
 Errors-To: grass5-admin at grass.itc.it
 X-BeenThere: grass5 at grass.itc.it
 X-Mailman-Version: 2.0.5
 List-Help: <mailto:grass5-request at grass.itc.it?subject=help>
 List-Post: <mailto:grass5 at grass.itc.it>
 List-Subscribe: <http://grass.itc.it/mailman/listinfo/grass5>,

The same filter has been applied also to 'weblist' (mailing list
dedicated to receive web site comments and requests).

Let me know in case of problems
