On my centos 4.x box

# echo "none /var/spool/MailScanner/incoming tmpfs 
mode=700,size=300M,uid=postfix,gid=postfix 0 0" >> /etc/fstab
# mount -a
# df -h /var/spool/MailScanner/incoming/
Filesystem            Size  Used Avail Use% Mounted on
/dev/shm              300M   14M  287M   5% /var/spool/MailScanner/incoming

This ought to be there on the wiki someplace.. btw the usage (including 
SpamAssassin.cache.db) never goes beyond 30-40MB on a server processing 
100000+ mails.
