[Mimedefang] whitelist_from not working

[Marco Berizzi]

Hello everybody.
I have installed a small linux system with
sendmail 8.12.11 + MD 2.52 + SA 3.04
I have added to /etc/mail/sa-spamassassin.cf

whitelist_from *@domain.ru

but spamassassin tag some messages as spam.
This is the maillog relative to the message:
