I had a problem with this but fixed it myself, so I thought I'd share it here:
I wanted to add an SPF record to my website's DNS using the 34SP control panel, such that I can restrict what servers can send mail with sender addresses from my domain (and prevent GMail from deleting certain incoming mails from automated scripts).

This looked simple enough, but when checking the record with an online tool, I saw that the spaces in the record had been omitted, making it invalid. I tried a few things and the solution proved to be escaping each space with a backslash. For instance, to allow any 34SP server to send mail using your domain, as well as any MX server defined in your records, this should be entered as data field for the new TXT record in the DNS management interface:
Code:
v=spf1\ ip6:2a00:1ee0::/32\ ip4:46.183.8.0/21\ mx\ -all


Propagation of DNS records can take a while, here is a handy tool that can be used to check the status.
