When I send an email to groups.io, I get a DKIM fail and SPF fail. I would like to work on SPF for now as I am just learning about this.
The error report says:
<source_ip>66.175.222.108</source_ip>
<count>6</count>
-<policy_evaluated>
<disposition>none</disposition>
<dkim>fail</dkim>
<spf>fail</spf>
</policy_evaluated>
?
My SPF record does have "include:groups.io".
Do I have to add "ip4:66.175.222.108"?
Someone mentioned that I need to add?ip4:66.175.222.12 too. Is that correct?
Thanks in advance for any suggestion. If this has been asked before, could you point me to the message? Many thanks!
David
