I have implemented this by using maildrop and calling spamc from it's
/etc/maildroprc
maildrop has a C like scripting language and has a lookup() function which
takes a look into a text file and tries to find the address from it.
A snippet from my /etc/maildroprc:
------------------------------------------------------------------------------
SCAN_SPAM=1
if ( /^From:\s*(.*)/ && lookup( $MATCH1, "/usr/etc/maildrop_sender_whitelist",
"D" ))
{
xfilter "reformail -a'X-Whitelisted: $MATCH1 in
/usr/etc/maildrop_sender_whitelist'"
SCAN_SPAM=0
}
if ( $SCAN_SPAM > 0 )
{
xfilter "spamc -H -x -d spamd -u spam"
}
else
{
xfilter "reformail -a'X-Whitelisted: because some reason earlier in
/etc/maildroprc'"
}
------------------------------------------------------------------------------
The script has variable SCAN_SPAM which is set to 0 (false) by several checks
and the system calls SpamAssassin only when necessary.
The script as shown works with maildrop 2.x, it has to be altered a bit when
used with older versions.
Maildrop replaces the more usual procmail in the mail delivery chain.
The file maildrop_sender_whitelist contains email addresses (or regexp) one on
a line, it would be ideal for your purpose.
