spamd and bayes question

["Jeffrey N. Miller" <mi...@cottonteam.com>]

I want to use Spamassassin with MIMEDefang and Sendmail as a SMTP Gateway.  Can you use spamd/spamc with this method or does it just invoke the script method?  Also, what is the best way to train spamassassin if I have a SPAM dump in MSExchange public folders?  Or is there a better way of training bayes?

1) Can't really help you there, as I don't use MIMEDefang.  Try 
http://www.mimedefang.org/.

2) Access the messages via IMAP using this script:
http://www.dmzs.com/tools/files/spam.phtml

The downside to this approach is that Exchange will strip off many 
useful headers when accessing messages via IMAP, but it's still a good 
start for Bayes training.  Your only other option is to resend the mail 
from within Outlook.  For that, see here:

Neither, mimedefang invokes SA directly at the perl API level. Since 
Mimedefang is already running in perl, invoking a separate process to use 
spamc/spamd would be slower.

The direct API level call is the fastest way for persistent perl daemons to 
call on SA. Effectively, these tools act as their own spamd by keeping an 
instance of SA always loaded and ready. However, the efficiency gain of 
using the API only works for perl daemons.

Perl scripts that execute, scan mail, and exit are better off invoking 
spamc. If they implement the API, they're no better than the spamassassin 
script.
