I agree with this but not for /var/spool/sympa which is really small and 
with poor access, it will not make your server faster to put it on a 
fast disk , in addition, that spool is used mainly by the distribution 
processus, not by the fastcgi server which need to be as fast as 
possible. /var/log /var/lib/mysql is much more important.

In early sympa version, all messages where archived twice, one copy was 
in ~sympa/expl . Now messages are archived only once usually on 
~sympa/arc but you can change this location (parameter arc_path in 
wwsympa.conf). ~sympa/expl will grow depending on shared repository usage.
