(1) Check your MTA options. Some allow you to configure rejection of a
message after X number of invalid recipients are given.

(2) Consider a rule that adds a point if more than X names appear in
the TO: and/or CC: headers. Here are mine (20 is the limit):

describe TO_TOO_MANY To: too many recipients
header TO_TOO_MANY To =~ /(?:,[^,]{1,80}){20}/
score TO_TOO_MANY 1.50

describe CC_TOO_MANY Cc: too many recipients
header CC_TOO_MANY Cc =~ /(?:,[^,]{1,80}){20}/
