Ignoring MX records - how common

Having changed the configuration of my MTA recently I noted that
a handful of genuine e-mails are delivered (and thus now lost)
to the A record for the domain wretched.demon.co.uk

The domain has MX records, and my reading of the RFC's (and
Eric's if his book on sendmail is to be believed) says these
should always be honoured if they exist, which agrees with
commonsense.

Anyone have a feeling for how big this "issue" is?

I wouldn't mind so much, but so far the only ones identified are
a UK DNS/Intranet consultancy, and a mail server at the company
that hosts my companies DNS domain.

So I wondered if there was some evil pattern emerging. To make
my life with DNS harder.

Someone here must log SMTP connection attempts to their web
servers, and have A records for all the domains hosted.
