I have been using zoho mail for my website (https://markedium.com). 

I couldn't able to get any mail from website and I also want to use different mail for different section like: contact, submission, registration etc.

Is there any way to integrate / use all the email for different purpose.

Also Zoho Plugin for WordPress giving error. Check the screenshot kindly.

Is there any way to use SMTP ports manually in wordpress to integrate Zoho mail with WordPress website.
