On the interfaces and ports that postscreen(8) passes mail to, yes.
If you have a dedicated submission port, this is not affected by
postscreen running on port 25.
Do note that the behaviour is different; you will be able to directly
transplant your reject_rbl_client RBLs to postscreen, but postscreen has
many more options available, such as checking for exact return values,
and scoring different RBLs with separate weight values.
