Purging bayes_seen file.

[Francis Stevens]

The bayes_seen file on my server has grown quite large (42MB), the man 
page for sa-learn documents what the file contains, records of 
message-ids that have been learned (in my case autolearned), but gives 
no clues of how to purge it or if this is a bad idea. Is there are 
method for shrinking this file (I'm already doing a regular sa-learn 
--force-expire --sync)? I've tried Google and the wiki but not found 
anything.  My first idea was to shutdown amavisd-new and remove the file 
altogether and then restart amavisd-new which will create a new, empty, 
file. Is this a "bad idea"?
