Automatic translation of emails???

Automatic translation of emails???

Hi Zoho Mail team,

Can someone tell me if a new automatic translation feature has been added to Zoho mail? I have been using Zoho mail for several years now and this morning I just started seeing all of my mail translated to English. I normally work on a daily basis in English and Spanish. 

I actually looked at an email sent by me and sent an apology to the original recipients for writing in the wrong language. And also thought I was losing it.

If this is a new feature, where can I turn it off?

Help!!!!
