Change to "v=spf1 a mx -all"
•• If you make the MX change that I suggest then the

I disagree with that. An MX is the receiver for inbound mail. It does
not follow that emails are sent out via the MX. Removing the explicit
listing of the IP addresses will just cause accidents in the future, if
the MX no longer happens to also send email.
If anything the 'a' within the SPF record could be removed, because
that's the HTTP box on DigitalOcean.
