I'm no expert, but imagine that that would be safer than just
quitting.

Or, how about switching to a special (new) mode in which a
spamicity of 0.000000 is always reported?  That way, no mail will
be lost (AFAICT), but the sudden increase in spam might prompt
the sysadmin to investigate, thus hopefully seeing that he or she
needs to tweak bogofilter's config.  :)

Note, i'm at least half-kidding about that idea.  But heck, maybe
it would work?
