I want to set up a SPF record, I used this 2 links as guidance:
I want to allow only emails from 2 IP:
Any other has to be strictly rejected, so far this is what I have
"v=spf1 ip4:18.104.22.168 ip4:22.214.171.124 -all"
I currently have this configuration for MX:
dig +short MX durerocaribe.cu 10 zion.durerocaribe.cu. 0 correo.durerocaribe.cu.
and for SPF:
dig +short TXT durerocaribe.cu "v=spf1 mx a:zion.durerocaribe.cu -all"
