Attached is a proposed patch for /var/lib/spamassassin/rules_du_jour
which addresses the problem of the refresh URL which Rules Emporium
sometimes sends out instead of a valid cf file. Basically, this patch
greps the downloaded file for the string "META HTTP-EQUIV", which should
never occur in a valid rules file, but is part if the refresh URL. If
the downloaded file is a refresh URL, it's deleted, the script waits 1
second and tries again, up to 3 times. If the download fails after 3
tries, the bad file is deleted and the script moves on.
You might try running rules_du_jour from a cron job with the -D option
and redirecting the output to a /tmp file and see if you get any notices
about "Download of .... FAILED after 3 tries", in which case I've
mis-diagnosed the problem somewhat. In any event, the problem file
should be deleted rather than causing a --lint failure in spamassassin.
