I can't receive emails, but I can send emails. If I use a different email to send an email to my zoho account with, I do not get any error messages.

I went to my DNS manager at godaddy.com to delete all records and then add them again. But I can't get my zb code to add cname as my domain is already verified by Zoho. And I do not want to delete my Zoho account completely to reinstall it all, as I believe I have a couple of important emails "hanging in the cloud" that I don't want to loose (as I believe I will loose the emails if I delete the Zoho account to reinstall)
