Why not use procmail w/ spamassassin. SA keeps a config file in
your home dir (.spamassassin/user_prefs) to which you can easily
add a whitelist and blacklist.

You'd be amazed what you can do w/ whitelisting/blacklisting! And
SA takes care of spam in one go. Procmail here is only used to
direct mail into the appropriate mbox.

ex.: simple config (SuSE):

----------------------------------------------------------
# SpamAssassin user preferences file.
# See 'perldoc Mail::SpamAssassin::Conf'
# for details of what can be tweaked.
###########################################################################

# How many hits before a mail is considered spam.
# required_hits         5

# Whitelist and blacklist addresses are now file-glob-style
# patterns, so "friend at somewhere.com", "*@isp.com", or
# "*.domain.net" will all work.
# whitelist_from        someone at somewhere.com

# Whitelist From + check against received headers
# whitelist_from_rcvd

# Whitelist TO (mailing lists)
