flexfax: Change time 'til faxes are deleted?

[=?Windows-1252?Q?Dominik_R=F6ttsches?= <webmaster@bvppt.de>]

Hi readers,

can anybody tell me with which config switch the time until faxes get
deleted can be changed? I searched the Hylafax FAQ and documentation but I
didn't find any solutions.
The problem is that I want to have faxes stored eternally. They should
definitely not be deleted after a few days.

Thanks to anybody for a quick response
