But this license-plate analogy only applies to the faulty MX record.
According to the original poster, that site had _two_ MX records:
MX 8 n.n.n.n. (faulty)
MX 10 mail.foobar.com. (correct)
Why couldn't Courier try the correct MX record after the faulty one
fails? I don't
I think the question is:
Why does it *need* to be fixed in the first place, except for the

that it's not RFC compliant?
The way the internet works is defined by the RFCs. Imagine if for some

Because obviously a significant number of people misinterprets the
RFC.
More likely, they just have no clue and never read this RFC.
I didn't read the RFC, but I have always used an A record for MX. It
just doesn't seem logical to put IP addresses in places other than A
records, the idea being t

Yes, it is. If the offending MX is
MX 10 n.n.n.n
you can put
n.n.n.n allow,BOFHCHECKDNS=0
in smtpaccess.

Okay, I'll do that. In this case, the DNS hosting firm is local, so I

hostname in the MX field if we cannot resolve it to an IP.
