OpenDKIM configuration has two Lua scripts defining strict DKIM policy. screen.lua filters out signatures that do not correspond to the From: domain so they are not even checked. final.lua rejects mail if it is not outgoing and has no valid DKIM signatures. OpenDKIM is configured as a milter on port 25 smtpd to check DKIM signatures and on mail reinjecting smtpd to sign outgoing messages with DKIM signatures.
