Assalamu Alaikum WW
Every century has them, one or more than one Maulana Maseehullah Khan (rah) was popularly known to be one. See the dream below. It is mentioned in Mahsaikh e Chist of Maulana Zakariyya (rah) also.
Once Hadhrat Maulana Maseehullah Khan (rah) saw Mu'eenuddin Chisti (رحمه الله) in a dream, who told him, "We are transferring Dua to you. Therefore, whoever comes to you for Dua, do make Dua for them.
Does anyone know of any present day Mustajabud Dua (One whos Duas are readily accepted) through accepted sources?
