It sounds like you only need to have a different outgoing MTA whilst
you may still use what you have for receiving emails ?

The setup for sending an email begins with the user's client, which is
configured to send via a chosen MTA (configured as smtp host for that
client). In addition you need to have set up an SPF declaration in the
DNS configuration for your sending email domain that the particular
MTA as allowed to send emails from your email domain.

And of course you need to have agreement with the MTA owner that they
do deliver from you. This can be done by having an account with an
email provider and then simply register "@pwduffy.org.uk" as an
additional "identity" for them. They will then send out emails from
"@pwduffy.org.uk" by means of an smtp login to your account. (You may
then also use that new account for sending and reciving emails under
its domain)

With such a set up, your emails from "@pwduffy.org.uk" will go out
from that MTA, and emails sent to "@pwduffy.org.uk" will be received
there as now.
