No. In the cases I remember, the MX had been set up for weeks
before the problem popped up. I guess the primary MX host has
not responded, so the mail got routed to our mail server which
has a lower precedence, and therefore not normally gets mail
for the customer.
I think you can understand I get scared when our mail server
rejects mail for our customers with a fatal error message.
DNS errors may be the explanation, but DNS was fine at the
times I checked it.
It has been helpful to me to get confirmed that the customer's
domain names belong in control/rcpthosts only, in my setup.
