rsync usage in spamd.conf

[Jay Moore <jay_mo@bellsouth.net>]

I'm trying to add the CBL (http://cbl.abuseat.org/) to my <spamd>
table.

The CBL is available via rsync (AFAIK it's not available via ftp,
http, etc); e.g.:

rsync rsync://rsync.cbl.abuseat.org/cbl/list.txt /path/to/list.txt

I'd like to add this to my spamd.conf file, but don't see any obvious
way to shoehorn the rsync command into the syntax of spamd.conf.

Can this be done? If so, an example would be a big help.

If not, I guess the alternative is to put the rsync in my cron file,
and simply add a plain old file reference to spamd.conf?

Thnx,
Jay
