nothing special
mailscanner, spamassassin 3.1.4 done update from 3.0.4 the day bevor 
the problems startet, but ive found nothing special in the release notes 
about bigger changes and .. sa is behind sendmail

i have some rules in sendmail access like

From:sued at gmx.de ERROR:"550 User unknown. We don't accept mail from spammers."

but thats only for mailadresses, not for tld´s

greetings
