[Mimedefang] set_reply returned MI_FAILURE

[Tim Boyer]

I've been running MIMEDefang for a while, but just recently started filtering
for bad filenames.  I'm using the stock mimedefang-filter example file, with
one exception:  rather than drop_with_warning here:

    if (filter_bad_filename($entity)) {
        md_graphdefang_log('bad_filename', $fname, $type);
        return action_drop_with_warning("An attachment named $fname was removed
from this document as it\nconstituted a security hazard.  If you require this
document, please contact\nthe sender and arrange an alternate means of
receiving it.\n");
    }

I've changed action_drop_with_warning to action_bounce.

Instead of bouncing, however, I'm getting the set_reply returned MI_FAILURE in
logs, and the message is not being rejected.

filter instructed us to

MI_FAILURE

It's doing everything absolutely correctly until that last failure.

I've got no idea what I'm doing wrong here - any help is appreciated.  Thanks
much...
