AW: [Mimedefang] Performance tuning MD w/ SA

Hi Justin,

>From mimedefang.pl:
 # Defaults
 $SALocalTestsOnly = 1 unless defined($SALocalTestsOnly);        

  $SASpamTester = Mail::SpamAssassin->new({
    local_tests_only   => $SALocalTestsOnly,
    dont_copy_prefs    => 1,
    userprefs_filename => $config});

so unless you explicitely set $SALocalTestsOnly=0, SA will run neither razor
nor DNSBL.

Sendmail points to mimedefang.sock; if mimedefang is started correctly, it
hands off the requests to the multiplexor instead of directly starting perl
subprocesses:

        echo -n "Starting mimedefang: "
        daemon $MIMEDEFANG -m /var/spool/MIMEDefang/mdefang-mx.sock \
                -p /var/spool/MIMEDefang/mimedefang.sock $SENDER_CHECK
$RELAY_CHECK \
                -P /var/spool/MIMEDefang/mimedefang.pid -U mimefilter
 
Bye, Martin
