Oh, now I see why I was confused about and vs. or!

This is especially important vs. the "acl =" acl item.

Personally, I'd say make it always mean "and", and do the "or" thing by
creating an acl, like this:

accept_recipient = accept_recipient_acl


accept_recipient_acl:
accept acl = local_acl
accept acl = relay_acl


IMO, additional clarity is worth those few additional lines in the config.
