v=spf1 ip4:79.170.40.14 a mx ~all (for fojd.org.uk) looks ok for
testing. (Change to "-all" when you are satisfied it works.)
You should probably protect mail.fojd.org.uk with:
v=spf1 -all
(to protect you from people spoofing with e.g. someone[at]mail.fojd.org.uk)
82.110.105.67 is IP address for webmail.outitgoes.com and from what you
say you seldom use it. So don't include it for your domain. Even if you
used Heart Internet's webmail system, it probably would not be sending
the email out with your cmoon[at]fojd.org.uk as the return address (or
would it?)
The mail server your message came from is mail14.extendcp.co.uk
(79.170.40.14), its "Helo" is mail14.extendcp.co.uk, which is the same
and should satisfy fussy mail handlers like mine, hotmail and others.

Your reverse DNS is not broken, it provides a valid name (ok it's not
your's but that doesn't break it...) as long as there is a name to
resolve to is enough. Many of us have similar situations.

(One thing you might do which would be good practise is to change the
"Helo" of your own server from LHHEBH778MZIL6 to something that
resolves, like fojd.org.uk, but probably not needed to make SPF work.)
Hope this helps, I am usually reluctant to post, as I am not completely
familiar with SPF, but it works for me... and I'd like to see more using
it.
