I am not entirely sure I understand your message.
Usually, SPF checking is only applied to non-authenticated messages. To
do this, you can either use Courier's built-in SPF support with `opt
BOFHSPFTRUSTME=1` (see the courier manpage), or use Courier::Filter's SPF
filter module with the "trusting" option set to true:
...
Courier::Filter::Module::SPF->new(
trusting => TRUE
)
...
That way, trusted (i.e. authenticated) messages are not handled by the SPF
filter module.
But you can apply SPF checking to authenticated messages, too! To do
this, you can either use Courier's built-in SPF support with `opt
BOFHSPFTRUSTME=0`, or use Courier::Filter's SPF filter module with the
"trusting" option set to false:
...
Courier::Filter::Module::SPF->new(
trusting => FALSE
)
...
