What you can tell your customer is that what they provided is not a
valid SPF policy (record) and it will result in a 'Permanent Error'
and that you will only post a valid and correct SPF policy.
If they don't believe you, you can send them to the address below to
Other than that, I can't tell you how to run your business but if any
of my customers were sending out UCE and I could prove it or if it
disrupted the service of my other customers then I would get rid of
that customer without losing any sleep over it.
