HOW TO RESEND CONFIRMATION ZOHO

Hello, i want to ask with people in here about resend mail confirmation like the first we register Zoho mail with our domain. 
i am a graphic designer so i make my website with adobe muse. My website have a contact form and direct send to my reservation mail in zoho. but it did not works. i try to send another mail from my gmail account and itu works delivered to my reservation mail in zoho.

in this case what can i do to fix this problem? i think i want to reset my hosting and start like the first i started but i can not find how to resend confirmation mail like the first i do before.
