Then please stop adding restrictions you don't need.
reject_unknown_sender_domain means what it says. if you don't need it,
don't use it. don't think that aligning all the access(5) keywords is
gonna help you get safe.

btw, there's rarely any valid reason to use
reject_unknown_recipient_domain. This was explained in recent threads
for the one who can follow:)

Some of the restrictions are for special use, and shouldn't be added
unless you really need them. so start with a simple set and add
restrictions step by step. Of course, always keep relay controlled.
that's the only thing you need to keep in mind.

good luck.
