Not familiar with these variants, but;
- what does 'hostname <Return> get you?
- Is 127.0.0.1 your actual external IP? If not, have you told Exim the real one
or defaulted to it? (DHCP assigned?)
- Have you confirmed with the folks at what used to be 'Mercury House' that you
want 'mail.bulldog.com' and not 'mx1.bulldog.com' for the smarthost, whether
they expect you on port 25 or a submission port, and if you are exepted to
authenticate, and if so, how?
And one presumes you are not *really* using 'example.com' for anything but
obfuscation.

Can you enter yourself as a permitted relay_host on that server?

An MTA does not ordinarily expect to connect the same way an MUA does.
If you want to act as an MSA client where an MUA is normally expected, you will
have to 'teach it' to connect on the submission port and authenticate as an MUA
would do.

You should be able to test almost entirely within your internal LAN by setting
up for 'IP literals' and/or running a local DNS with test domains and pointing
to it at the top of ~/etc/resolv.conf (or Linux equivalent). ~/etc/hosts (or
Linux equivalent) along with some additional Exim settings might also do.
If you are going to run a public-facing smtp server, you should check Bulldog's
T&C carefully before you proceed. Many broadband providers forbid that.
