Our DNS is managed through Microsoft. I need to set up a new record to allow a new website to send email. Here is what I did.
1) I set up the following SPF record
host: subdomain
value: v=spf1 ip4:xxxx ip6:xxx include:subdomain.domain.com -all
2) There is an existing SPF record
host: @
value: v=spf1 include:spf.protection.outlook.com -all
When I test it, I got the following error
PermError SPF Permanent Error: include has trivial recursion: include:subdomain.domain.com
Can someone tell why and how to fix it?
Also for the new SPF if I add the host as @, how should I add the value?
Thank you so much!
