Getting one stranger SoftFail

Hi Folks,
I’m getting one stranger SoftFail in my PHPList installation. I will be very glad if someone help me.

This is my Instalation:

Powered by phplist, version 3.2.5

And my SPF txt entry on my domain (

v=spf1 mx a ip4: ~all

And this is some detail of email header

Received: from ( [])
spf=softfail ( domain of transitioning does not designate as permitted sender)
From: Marcelo J Bresciani

I wrote a Simple Script calling PHPMailer, and this script Works fine.I think something is happening with my PHPList.

Someone can Help me?

Somewhere in the phplist settings or configuration you have specified this email address.
What value do you have in config.php for this line

$message_envelope = 'xxxxxxxxxxxx';

This should be an email address on your own domain.

Hi Duncanc!!!

Thank you for your readiness reply!!
I check this variable, and noticed I don´t have in my config. I’m setting this and starting to make another test. Let me do this…

thank you!!

Now it works fine!!!

Received-SPF: pass ( domain of designates as permitted sender) client-ip=;

I really don’t knew the utilization of this variable for SPF validations…

Thank you!!
