I get Event.id 4000 smtpsvc
Message delivery to the remote domain 'adomain.com' failed for the following
reason. SMTP could not connect to any DNS server.

When I open nslookup, I get
Default server: ms2003.myweb.com
Address: my ip address

I then enter:
set q=mx
myweb.com

and get myweb.com mx preference = 10, mail exchanger = ms2003.myweb.com
ms2003.myweb.com internet address = [server ip address]

In smtpvs I have Delivery to FQDN ms2003, and Authentication is anonymous,
no relay

In my dns I have 3 nameserver names (ms2003, myweb.com & ms2003.myweb.com),2
Host A (myweb.com & ms2003.myweb.com) and 1 mx (ms2003.myweb.com [I have
tried this with just myweb.com])

In my mail client my pop3 and smtp at to myweb.com

I'm obviously doing something wrong, but what?

I'm not sure I understand completely but I'll take a stab. Do you have
external DNS servers defined on the Delivery Tab/Advanced button/Configure
button in the properties of the SMTP virtual server? If so are they valid
(try to perform an nslookup against them, instructions below)? If not then
who is the OS pointing to for DNS? Can you connect to those using nslookup?
It looks as though your smtp virtual server can't connect to a DNS server
much less make a query.

nslookup<enter>
server x.x.x.x<enter> => where x.x.x.x is the ip of the DNS server you are
pointing to
then the rest of your query like normal i.e.
set type=mx<enter>
microsoft.com<enter>
