One thing I have added to the SPF record is "include:lists.alug.org.uk" although I don't know if that is helpful/wrong.
lists.alug.org.uk does not have an SPF or TXT record (nor does alug.org.uk), so that is definitely wrong. I suspect it is unhelpful.
If you really wanted to add it, I think "mx:lists.alug.org.uk" might do what you were aiming for.
(I've not replied to the DMARC bits because I don't remember it well enough and have not time to look it up.)
Hope that helps,
