Outgoing mail shows in mail headers: Domain of transitioning does not designate as permitted sender

Symptoms

• One of the following entries are shown in the headers of the outgoing mail:

  CONFIG_TEXT: Received-SPF: softfail (google.com: domain of transitioning mail@example.com does not designate 203.0.113.2 as permitted sender) client-ip=203.0.113.2;

  OR

  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;

  OR

  CONFIG_TEXT: Received-SPF: neutral (google.com: 203.0.113.2 is neither permitted nor denied by best guess record for domain of jdoe@example.com) client-ip=203.0.113.2;

• 203.0.113.2 is an IP of the server or a trusted IP.

Cause

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.

Resolution

Note: if DNS is managed by a 3rd party DNS server, the record should be configured there.

1. Go to Domains > example.com > DNS Settings.

2. 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"

   

3. To apply changes to the DNS zone press Update button.
