MIMEDefang includes support for the SpamAssassin SPAM detector. To
use SpamAssassin with MIMEDefang:
1) Download the latest SpamAssassin tools from http://spamassassin.apache.org/
2) Install the SpamAssassin tools.
3) Configure, make and install MIMEDefang.
4) Use the one of the functions spam_assassin_is_spam or
spam_assassin_check in filter_end(). See the sample filter in
the examples/ directory.
The sample filter adds a header if SpamAssassin thinks the message is
SPAM. You can then use MIMEDefang to control message disposition on a
global basis, or procmail to control it on a per-user basis.
SpamAssassin is pretty slow, so it's better to run SpamAssassin from
MIMEDefang, and let per-user tools like procmail control message
disposition based on the presence of the X-Spam-Score header.

READ THIS SECTION NOW BEFORE POSTING QUESTIONS ON THE MIMEDEFANG MAILING
LIST:
MIMEDefang does *NOT* allow SpamAssassin to modify e-mail messages.
If you set up SpamAssassin to add headers or tag subjects, it
will not work. Instead, you must have MIMEDefang do the modifications.
For example:
if (spam_assassin_is_spam()) {
# Change Subject: header
action_change_header("Subject", "** SPAM ** $Subject");
}
See the sample filter for more details.
