The sending IP is included in the mail headers. Looks like this:

All SMTP server should prepend the ESMTP id for any message they 
receive, and also the address it was arriving from, and the address it 
as received for.

Maybe I'm wrong, but I think RBL checks and other spam checks work on 
all IP addresses/domains that can be found in the "Received:" headers.  
Spamassassin works on email files that are stored under 
/var/spool/MailScanner/incoming. postfix puts received messages "ON 
HOLD" into this directory, and mailscanner moves that message back for 
delivery after scanning it.

Maybe I should post this question to the mailscanner list (however, I 
feel this is also related to FreeBSD MailScanner and spamassassin ports)
