1. I have the domain of http://www.ycg.ooo so my mail id’s also have (.ooo) domain like sales@ycg.ooo but in the admin panel on configration>>store Email address>>general contact, when i am giving sales@ycg.ooo then it is showing error and accepting only ( .com) domain but i do not have .com domain, i have ( .000) domain. So please help how to fix this error.
I am also attaching the snap shot of error.

2. The next question is you have provide mail templates like order, share wishlist, newsletter and many more but i am unable to understand how we shoot these email templates like we do not have any trigger for these templates.

3. For the .ooo domain it is also not accepting for newsletter subscription for this it is showing error (There was a problem with the subscription: Please enter a valid email address.) and this error is showing above of the product tab but it should be come on the below or above of the newsletter subscription box.
