FW: [Fwd: Warning: could not send message for past 4 hours]

[Mark_Andrews at isc.org]

	Firstly workout which machines are supposed to be serving
	w-sys.co.uk then make sure that they *all* have the same
	zone content.

	If you remove dns.w-sys.co.uk and/or mail.w-sys.co.uk
	from the delegation don't forget to also remove the
	associated host records.

	dns.w-sys.co.uk and mail.w-sys.co.uk don't have A or MX
	records for w-sys.co.uk which is what is causing the
	intermittent mail failures.

	Mark

	From the parent servers.

w-sys.co.uk.            172800  IN      NS      dns.w-sys.co.uk.
w-sys.co.uk.            172800  IN      NS      mail.w-sys.co.uk.
w-sys.co.uk.            172800  IN      NS      ns1.everydns.net.
w-sys.co.uk.            172800  IN      NS      ns2.everydns.net.
w-sys.co.uk.            172800  IN      NS      ns3.everydns.net.
w-sys.co.uk.            172800  IN      NS      ns4.everydns.net.

	From dns.w-sys.co.uk and mail.w-sys.co.uk

w-sys.co.uk.            3H IN NS        dns.w-sys.co.uk.
w-sys.co.uk.            3H IN NS        mail.w-sys.co.uk.

	From ns[1234].everydns.net

w-sys.co.uk.            1D IN NS        ns1.everydns.net.
