Not entirely. It isn't supported in the current milter interface,
but it is in sendmail 8.14. See:

The MIMEDefang interface to that API isn't available yet, though, see:
http://lists.roaringpenguin.com/pipermail/mimedefang/2007-February/031946.html

But hey, it's open source, I'm sure patches are welcome :)
