The Faximum software requires space on disk to store outgoing faxes before
they are transmitted and received faxes before they are claimed.
By default this spool area is located in /var/spool/fax.
The system administrator may change this by editing the appropriate
parameter in the /etc/faximum.conf configuration file.
If this is done, the Faximum daemons will need to be restarted.
