How do I unblock my domain and send mail to yahoo users?

[Md. Mujahidul Islam Khan]

We can't send email to yahoo users from our domain. We are using g suite. I have completed all the security settings by the guideline of g suit Admin help. After sending the email we receive the following error:

554 Message not allowed - [PH01] Email not accepted for policy reasons. Please visit https://postmaster.verizonmedia.com/error-codes

I couldn't found any solution. Please help me by providing a solution. This is very important for me.

Thanks

You were correct about trying to contact the Verizon postmaster for Yahoo Mail issues.
