I've been using the whitelist with success up until this point. I've
got a particular person that is trying to send in to us with the last
name of vollum. "Vollum" is getting caught by the fuzzy valium filter
and tossed as spam. I tried adding his email address as well as the
domain into the /var/etc/amavisd/whitelist_sender to no avail.

I've got "read_hash(\%whitelist_sender,
'/etc/amavisd/whitelist_sender');" in the amavisd.conf.

He's at the top of the file now.

Any ideas on what could be wrong?
