Hello guys.

I have a workaround when the customer's email account is being sent over a local broadband dynamic IP. I will share it here.
It's simple, just use some dynamic IP hostname service like "" in the SPF record.

• In my house I have internet with dynamic IP.
• I registered an account at (free or paid, it doesn't matter).
• I create a hostname for my home in, eg.
• I downloaded the DUC (noip client) and installed it on my home computer.
• Then I add the hostname in the SPF record for my domain, in cpanel, like this: "v=spf1 +a +mx ~all"

Now gmail no longer gives SOFTFAIL, but PASS And the message is no longer marked as spam.

I will be sending out a newsletter to my complaining customers to get them to do this too.

Best regards!
