We are building mail server to send mails for other domains.
We have multiple IP address and i have created "A" record like
spf.example.com pointing to multiple IP's
Now I have asked client to include our
spf.xyz.com in their SPF record to authorize send mails behalf of them.
We are getting error like
"- PermError SPF Permanent Error: No valid SPF record for included domain:"
What would be the problem? Is the process we are following is right?
