Mail problem on all Hostdime / Surpasshosting servers

Hi all. We have reseller hosting accounts on Hostdime and Surpasshosting servers. I'm trying to send emails to Gmail, Hotmail, etc. But emails do not reach the recipients. Only internal emails are received (therefore, between Hostdime servers). I am able to receive emails. We also have a hosting company, too. We can receive orders by script order form. But our customers can not receive emails from order statements that send the script. We did not receive any error. The staff of Hostdime confirmed the problem. But he could not fix or understand the reason.

If you are a Hostdime / Surpasshosting client; Have you experienced the same problem today?
