[Mimedefang] Spamassassin autowhitelist with MIMEdefang

[Mike Van Pelt]

Is there a way to turn on SpamAssassin's autowhitelist feature
when using MIMEdefang as the milter?

What I'm after is the auto-whitelist, where it keeps track of
the average spam score of email from each sender, and biases
the spam score of an email based on that sender's past performance.
This is enabled by the -a option to spamassassin when it's called 
directly, but when MIMEdefang absorbs spamassassin's functions...
how do you turn it on then?
