With your Easily email account, you have to use our MX records (easymx2.easily.co.uk and rhea.easily.co.uk), and only our MX records. Sometimes, people add a 3rd server as a back up service, to make sure that if the first 2 go down, the 3rd one take the relay.
In your situation, you only have our 2 MX records, so to the question “Do any other servers send mail from suehutton.co.uk?” the answer is “No”.
Same answer for “Could mail from suehutton.co.uk originate through servers belonging to some other domain?”, “No”

And for “Do the above lines describe all the hosts that send mail from suehutton.co.uk?” the answer is “yes” (meaning easymx2.easily.co.uk and rhea.easily.co.uk).
I hope that will help.

This wizard found 2 names for the MX servers for suehutton.co.uk: easymx2.easily.co.uk and rhea.easily.co.uk. (A single machine may go by more than one hostname. All of them are shown.)
MX servers receive mail for suehutton.co.uk.
Do they also send mail from suehutton.co.uk?

Do any other servers send mail from suehutton.co.uk?

You can describe them by giving “arguments” to the a:, mx:, ip4:, and ptr: mechanisms. mx: takes domain names and approves all the MX servers of these domains. To keep the wizard short we left out ptr:, but it works analogously.

Could mail from suehutton.co.uk originate through
servers belonging to some other domain?
If you send mail through your ISP’s servers, and the ISP has published an SPF record, name the ISP here. [include:]
Do the above lines describe all the hosts
that send mail from suehutton.co.uk?

I’d really like some help in understanding how I should answer these questions.

Thanks for the headsup on SPF though.

Sending emails from a Gmail account, through your domain name is called spoofing.

By spoofing other email addresses, you are more likely to be blocked by ISPs who can check if the domain name is using proper email servers or email forwarding.

Your solution would be to use an ALL SPF record like below:

“v=spf1 ~all”

It can help in the sending of your emails, but you are also more exposed to the risk of being spoofed yourself.

The most annoying situation is when a spammer is using your email address to spoof and spam thousands of random addresses, because you are the one receiving the thousands bouncing back messages.

Hope it would help you understanding a bit more what are Spoofing and SPF records.

Thanks for your comment.
The SPF record would be customized depending of which addresses you would like to block or which servers you would like to accept.
