The stress=yes setting indicates that a master.cf service is using
up all its process slots. It is applicable only for servers that
accept connections from remote clients.

By design, postscreen runs as a single process. The stress=yes
parameter value therefore carries no useful information. Either
the postscreen service is not running at all, or it uses up all
its process slots because there is only one.

I could make a special case for single-process servers in master.cf
so that they don't have a stress parameter.
