Sorry, I can explain a bit more.
itsupplies.net is currently hosted on Uk2.net, I have DNS mgmt and have
purely changed over the MX records to point to my server (yes I know, only 1
server for both...its a test!)...
Uk2.net obv. uses sendmail, in fact I think they run RAQ3 servers (pre-built
linux www servers) so they do run s/mail.. that 'itsupplies' ip is prob an
ip for many many virtual domains...
Is it possible then that the SMTP traffic is not actually getting through
somehow?
I thought as long as MX points to me, SMTP should follow that route and not
get caught up!?....
I have no packet filtering on my machine, and DNS purely points to my
router, which points to PIPEX dns....
It must be getting caught somewhere?

The same hostname at two different MX values isn't "fine", but isn't
causing this problem.
If I try to connect to mail.itsupplies.net on port 25, the packets are
blackholed. Are you sure that you're not packet-filtering TCP/25?
If I try to connect to itsupplies.net on port 25, I get a connection.
This is strange, since mail.itsupplies.net != itsupplies.net, and the MX
records mean mail for itsupplies.net will _always_ go towards
mail.itsupplies.net. So the only reason for an SMTP service to be
publically listening on itsupplies.net is if it's there for some other
domain.
: %; telnet itsupplies.net 25
Trying 212.4.208.121...
Connected to itsupplies.net.

Sendmail? Sendmail 0.0.0/0.0.0 ? It returns ENHANCEDSTATUSCODES in the
EHLO response, so this isn't Exim dressed up to look like Sendmail in
the connection banner.
Sure you have your DNS and packet-filtering set up correctly?

If Windows is the solution, could we please have the problem back?
