I was completely unable to login or signup to the forums with that account, but that's not the problem I'm trying to fix with this post.
I am having trouble setting up the SPF authentication; I did everything detailed in the guides, and I even waited 24 hours for the changes to propagate, but it seems as if it's not setup, because my sent mails get put into spam folders of the recipients, and the SPF section in the authentication section of the dashboard doesn't show up.
I added a TXT record with the value
v=spf1 include:zoho.eu ~all
But that doesn't seem to work. I've seen on the forums some people using zoho.com instead of zoho.eu, but the guides specify using zoho.eu
