Can you explain why we should operate non compliant mail servers? JUST to
get mail from other non complaint mail servers?

Sure, RFC1912 is not law, but its there and its there for a good reason,
so do we now start to ignore other RFC's ? or just the ones we dont like?

When these people get all there bounced mails they soon get the picture,
complain to their IT unit who in turn should get off there lazy asses and
fix what should have been setup correctly in the first place!
There are just too many lazy incompetant idiots in the IT industry.
