Unable to send message;Reason:554 5.1.8 Sender Address Blocked

Hello,

Can you unblock my account as well. I cannot sent emails out. I receive this message below and responded to it, but still haven't heard back anything yet

Hello Murad,

Greetings from Zoho Mail!

On observing, our Spam processing algorithm has identified suspicious content/keywords in the emails which are being sent out using your Zoho Mail account (claims@uzautotransinc.com). Due to this reason, your Zoho Mail account is blocked from sending out emails. Zoho Mail is designed for business exchange conversation and it does not encourage marketing/product promotional emails. However our abuse control team would like to know the nature of business using Zoho Mail for claims@uzautotransinc.com so that we can check the feasibility of unblocking your account. Looking forward for your favorable response. 

Regards, 
Balakumaran C
