One of the following entries are shown in the headers of the outgoing mail:
Received-SPF: softfail (google.com: domain of transitioning firstname.lastname@example.org does not designate 203.0.113.2 as permitted sender) client-ip=203.0.113.2; Received-SPF: fail (servername.example.com: domain of example.com does not designate 203.0.113.2 as permitted sender) client-ip=203.0.113.2;
203.0.113.2 is an IP of the server or a trusted IP
There is no SPF record for example.com, or an IP is not listed in SPF record for example.com
Go to Domains > example.com > DNS Settings > Add Record.
Create a TXT record and add the IP (in our case 203.0.113.2) as a permitted sender.
The record will look like this:
TXT example.com “v=spf1 ip4:203.0.113.2 ~all”
