Amavis is where you can whitelist mail addresses. Any address whitelisted in Amavis will bypass all spam checks in spamassassin. It will not, however, bypass any anti-virus or banned attachment blocking (by default).
If you look at the headers of a whitelisted email then you'll see that it reports [WHITELISTED] as the spam level.
EDIT - Sorry, forgot to mention. Whitelisting in spamassassin will still work as local.cf is still called by amavis. If you're using the amavis SQL tables you can define whitelists based on recipient policies rather than a global whitelisting
