I recently signed up for Zoho email account.  Everything is working fine except email addresses geting blocked when failed recipients exceed 10 per day. 

How do I configure my email addresses so that sender email are not blocked as soon as 10 failed delivery emails  ?  We can not ask support folks every time to unblock it.  Also, we don't have constant human support to check if emails are blocked and then unblock them.   Please let me know how to configure or increase this limit.

Thank you.
