[Mimedefang] MD-Quarantine dir cleanup script?

[Cormack, Ken]

The problems I've seen with both the xargs and "-exec rm" methods, though,
is that they can die if the resulting list of "hits" is too long.  That's
why I ultimately went with the while-loop.  It aint pretty, but it always
works, regardless of how many dirs are returned by the find.

doing an exec per match can be pretty CPU-intensive (lots of execs).  You
can also use xargs:

find /var/spool/MD-Quarantine -type d -ctime +7 | xargs rm -rf

(and adding "-maxdepth 1" if your "find" supports it will make it even 
faster)

I'm actually using "tmpwatch" on RedHat:

# This cleans up the old quarantine directories (more than a week old)
0 7 * * * root /usr/sbin/tmpwatch -cf 168 /var/spool/MD-Quarantine
