[Mimedefang] /var/spool/MIMEdefang

[Vivek Kumar]

Hi all,

There are following 3 files in /var/spool/MIMEDefang directory, which
are pretty big in size. 

auto_whitelist
bayes_toks
bayes_seen

What are these 3 files for ?? Does these files always grow ?? Can we
empty these files ( for space) ??

Thanks

Vivek
