  Use as many of the following as necessary.

  Put a message into a file and call slocal directly on it.

    $MHLIB/slocal -user $USER -verbose -debug < test-msg

  Modify your .forward to look like:

    "|/bin/sh -c 'exec >> /tmp/out 2>&1;
    $MHLIB/slocal -user $USER -verbose -debug'"

  Or modify a rule in .maildelivery to look like this:

    to foo | R "set -xv; exec >/tmp/out 2>&1; $MHLIB/rcvstore +foo"

  The previous examples are broken up for readability; the text must
  appear on one line.
