spamassassin whitelist problem

I am having fits trying to get spamassassin to stop bouncing legitimate messages from my own domain. No matter what I do it appears that spamassassin is ignoring the 'whitelist_from_rcvd' parameter (or I am not getting the syntax correct). I have one specific user that needs to send a pure html file which is normally blocked by spamassassin. Here is everything I've tried so far: whitelist_from_rcvd mydomain.com whitelist_from_rcvd myhost.mydomain.com whitelist_from_rcvd @mydomain.com whitelist_from_rcvd @myhost.mydomain.com mydomain.com whitelist_from_rcvd *@myhost.mydomain.com mydomain.com whitelist_from_rcvd myuserid@myhost.mydomain.com mydomain.com I'm sure there are other possible combinations and iterations but I wanted to stop guessing. Can someone tell me how to get this to work. Also does postfix have to be reloaded after each change to the spamassassin local.cf? TIA.
