We reject anything whose mid does not include the fqdn or address

for those few senders who are legitimate but have lazy and

Wow! You must not have any spam problems because you don't accept much
email -- ham or spam. :) I think some mail systems will keep the same
message-ID per email thread so your system must reject some replies.
There is no way that most of us on this mailing list can be as strict or
our customers would complain constantly about missing email.
