Hi Rajesh,
Back in July you posted a response to the mailing list with the subject
"[Mimedefang] dsn=4.0.0, stat=I/O error: I/O error" in which you wrote:

We're seeing the same symptoms -- stat=I/O error from sendmail when our
caching nameserver is running. The errors stop occurring if I go back
to the old remote-nameserver type of DNS. Did you ever find out what
the problem was? Is there a fix that will let us run our local,
caching-only DNS and sendmail both, without conflict?
Thanks very much for any help you can offer.
-- Kai
