Configure SPF for zoho.com

Hello,

I have a problem here and I can not resolve...

I used the configuration - v = spf1 to mx include: vedspf.vedomi.com include: servers.mcsv.net include: zcsend.net? All

So, I changed to - v = spf1 to mx include: vedspf.vedomi.com include: servers.mcsv.net include: zcsend.net include: zoho.com ~ all

What's the problem? Is it because I'm keeping "include: zcsend.net"?

How do I configure? I followed the steps and nothing ... Note: I am in Brazil and managed directly from the panel of Registro.br.

I appreciate any help.
