The postmaster address is special.
If a sysadmin screws up their recipient restriction configuration,
then someone can inform the postmaster that they screwed up.
If they broke their configuration so badly that it does not receive
email anymore, then people will usually notice.
So this is for sysadmins that screw up only mildly.
