[Mimedefang] How to setup spamd?

[Ken Morley]

I'm using MIMEDefang, which is calling SpamAssassin.  

I understand that it's more efficient to call spamd instead of loading and
executing spamassassin for each email.  While it's very easy to setup SA to
operate as a daemon, I don't know where to modify MIMEDefang to call spamd
instead of spamassassin.

What files do I need to modify?  Are many of you operating SA as a daemon?

Thanks!
