Whilst I think it is silly to do.
Why not drop emails that claim to be viruses or spam?
Of course why anyone would allow their servers

I'm hoping someone on the list can help confirm that I'm not going
insane.
I have a customer with the domain 'mtrsd.k12.ma.us' The domain
should be handled by our DNS servers (dns-auth1.crocker.com dns-
auth2.crocker.com)
The customer has an A record for www.mtrsd.k12.ma.us

How can you be sure it's not the other way around? You're sane and
everyone else is insane? :)

If you knew what I was thinking, you'd understand what I was saying.
I just tested it from a Verizon DSL host and it worked.
You might want to consider reading RFC 2182 though, particularly the
part about geographically diverse nameservers.
Yeah, yeah, that is overrated. If my site goes dark and my DNS goes
down it doesn't really matter as the bandwidth
If you are talking about strictly http, then you are probably right. If you
are hosting any email, then this isn't the case. A live DNS but dead mail
server will cause your mail to queue up for a later resend on the
originating mail servers. A dead DNS will cause the mail to bounce as

I'll defer to you on this. Clearly a failure to resolve is
not the same thing as a NXDOMAIN RCODE.
And yet, personal experience has show that the failure of all a
customer's DNS servers for a domain does cause swifter mail bouncing than
would occur otherwise. I do not know if it was due to the

A MTA bouncing mail on temporary DNS failure would be out of spec,
horribly.
luckily no mail servers are out of spec.
