Sendmail should reject it. Once the mail is getting far to hit 
Spamassassin you are wasting resources. From above rule the syntax is 
incorrect: there must be no whitespace between "From:" and the address. 
If the sender always uses the same sending host you may prefer

Connect:1.2.3.4        REJECT
