Email outgoing has been blocked

Hi Admin

One of my team member just told me that his email has been blocked and not able to receive and send emails .

his email is furqanul@mediatrenz.com 

Kindly check it and please make it unblock asap so we can resume our work as this is causing lot of problem since we are not able to receive any email.

Looking forward for your response.

Thanks 
Prabhat
