KAM.cf is a collection of SpamAssassin rules published by KAM (one of the project leads) - and our experience shows that it helps in catching spam. Currently updates to KAM.cf are only provided when we upgrade proxmox-spamassassin, as opposed to the daily updates for the SA core rules (via sa-update).

Since the rules get updated regularly, they should get updated on a running installation along with the rules provided by SpamAssassin directly. The patch adds the functionalilty for downloading KAM.cf to pmg-daily, which gets run (daily) by `pmg-daily.timer` LWP::UserAgent's mirror method is used since it adds a 'If-Modified-Since' header to the request, based on the provided localfile, sets the mtime to the Last-Modified date and replaces the file only if the download was successful.
