Of course, you should realize that the message header values can be
forged to be -anything- that a spammer wants them to be, and they have
no relation to where the mail actually gets routed.
The thing that acually controls delivery is something called the
envelope recipient and can be completely different from the 'To:'
header. Depending upon how your mail system is configured
Spamassassin probably has no way to "see" the value of the envelope
recipient.
This sort of thing is far better handled by your MTA, which has to
deal completely with the envelope recipient address.
