SPF Settings - Pass instead of neutral

[PlayCayP]

Hello,

I would like to ask you how I can get a SPFass instead of a SPF:Neutral?

For example if I send a mail to a gmail user, then it shows:

Received-SPF: neutral (google.com: xx.xx.xx.x is neither permitted nor denied by best guess record for domain of [email protected]) client-ip=xx.xx.xx.xx;
Authentication-Results: mx.google.com; spf=neutral (google.com: x.xx.xx.xx is neither permitted nor denied by best guess record for domain of [email protected]) [email protected]
X-No-Relay: not in my network
Received: from [x.x.x.xx] (unknown [xxx.x.xxx.xx])by server.xxxxxxxxx.com (Postfix) with ESMTPSA id 6Dxxxxxxxxxx

At Plesk I am using the following setting:

mydomainname.com. TXT v=spf1 +a +mx -all

I hope that you can help me with that.

Thank you in advance!

Remember if you are using your registrar's name servers then you will have to add the spf record there to.

Thank you for that information!

Since I use my own nameservers, it shows SPFass
