As long as I can recall, SA has always had Mail::SpamAssassin::Client say: "NOTE: This interface is alpha at best..." I've examined and used it,
though, and I must say it feels pretty 'beta' already to me. :) And it just feels a lot cleaner than shelling out to spamc from within a Perl daemon (like I do now). So, other than than Mail::SpamAssassin::Client possibly being subject to change, is there any particular other reason not to use it? Thanks, - Mark
