- Plesk for Linux
One of the following entries are shown in the headers of the outgoing mail:
CONFIG_TEXT: Received-SPF: softfail (google.com: domain of transitioning email@example.com does not designate 203.0.113.2 as permitted sender) client-ip=203.0.113.2;
CONFIG_TEXT: 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;
CONFIG_TEXT: Received-SPF: neutral (google.com: 203.0.113.2 is neither permitted nor denied by best guess record for domain of firstname.lastname@example.org) 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 the SPF record is misconfigured: it has incorrect format or an IP is not listed in SPF record for example.com.
Note: if DNS is managed by a 3rd party DNS server, the record should be configured there.
Go to Domains > example.com > DNS Settings.
Add Record/update an existing TXT record and add the IP (in our case 203.0.113.2) as a permitted sender:
The record will look like this:
CONFIG_TEXT: TXT example.com "v=spf1 ip4:203.0.113.2 ~all"
To apply changes to the DNS zone press Update button.
Refer to the following article to verify SPF record for the domain:
