Hi, my outgoing mail: ericazou1@zoho.com  has been blocked. 
Can you unlock it? 
Thanks a lot! 
Moreover, is there anything i can do to avoid exceeding the DAILY 10 bounceed count, besides deleting invalid and expired mail id's?
And if  if I exceed the DAILY bounce count, will my mail be unlocked next day?
THX.
