I set up emails on zohomail platform for my website to handle email deliveries, I built the website on wordpress CMS, I tried configuring Zoho emails with my wordpress using Flunet SMTP plugin but it is not being connected to the server,when I contacted the support they asked for the SMTP logs and I provided them, actually I hosted my website on cyberpanel server and I handle the server. 

Actually, the server is connecting to mx3.zoho.in instead of connecting to smtp.zoho.in

How can fix this?

Thanks and team please help me here
