I hope there is function to bypass envelope sender,for the envelope sender in the list (Like bypass users,admin can add address online),no more filter for header,contect,attachment,customs filter,visrus scan and etc.

As long as it is not forged then bypass. Better add this after FrontDoor and SPF.

1: spf passed,do by pass sender action

2: spf missing,softfail,fail,Neutral,PermError
