what happendend to the spam filter options

Hi Joe

I have read on various Topics on the Forum to switch spammassassin do spamd and clamav to clamd. You wrote "The option is labeled "Full path to clamscan command". Set it to "clamdscan" instead of "clamscan"" on another Topic but the options are gone in the newest version. How does the mail handling work now. And why uses the lookup-domain-daemon.pl over 100 megs of RAM.
How can i switch now?
regards Martin
