MX record for no-mail domainnames?

I've got some domainnames which are just used as http redirects.
My mailservers don't accept mail for them.

So, I just deleted the MX record in order to advertize to the world
that I don't want mails for these domains. But then I noticed that
postfix tries to deliver mails anyway and simply uses the domain name
itself as MX. I found in the RFC 974 that this is the correct way to
handle the special case of no MX records.

So, postfix is doing a good job!

But then, how should I configure my DNS?
Any idea?

Thanx,
 Andy.
