I am the owner of a reseller hosting, and one of my clients made the practice of spam. And all mail coming from my domain are not received by our clients in yahoo. (The IP of my server is being blocked)
The customer responsible for this practice has already been punished, however I am trying to solve this problem with yahoo. and am not having answers.
I wonder how I can get my PIP released on yahoo, so that our customers who have yahoo account can receive our emails (for reported payments and the like).
This problem is causing us a great inconvenience, I wonder how I can get in touch with yahoo to get this problem solved.
