I think "you can't get there from here" unless you do some serious  
kung fu action on your setup. MailScanner "touches" the e-mail, so the  
signature will *always* be wrong. The only way I see it working is if  
MailScanner hands off the e-mail to another server (or other separate  
sendmail process) that DKIM-signs the outgoing e-mails.
