This does not seem to be the case. I'm thinking that perhaps MD changes
the contents of the mail when parsing it, maybe some header changes.

<mimedefang.pl>

sub spam_assassin_mail (;$) {
...

 if ($sa_ver >= 3) {
        if (!defined($SASpamTester)) {
            my $object = spam_assassin_init(@_);
            return undef unless $object;
        }
        return $SASpamTester->parse(\@msg);

...
}
</mimedefang.pl>

Thank you, I didn't know that. The config had no effect, however.
