What does it mean when the maillog shows these first two lines?  Both
milter-null and milter-link are processing these two messages.  I have tried
adding milter-link-Connect:127.0.0.1 REJECT to my access.db.  It does not
change the milter-link lines.  The first message is a forwarded message.

It appears that milter-link ignores the contained banned URI because it
already already signed the message header.

When the message originates on the server, the same thing occurs and
milter-null DOES NOT mark the banned URI:

Milter-link does not appear to have checked the banned URI against the
access.db.  There are no records for a milter-link-body check of the
access.db.
