Incoming Fax Storage

I’ve noticed that all of the faxes that have been received and routed are being kept in /var/spool/asterisk/fax

Is there somewhere where an archive date can be set or to be deleted immediately after emailing? Some of the documents received contain confidential info which creates an administrative headache keeping that material on our servers.

Maybe you could Google “delete files based on date” and see if that gives you some ideas.
