I've played around and tried everything in my DNS records (even changing domain hosts) so that I will get the domain keys authenticated.

On checking with http://dkimcore.org/c/keycheck, it shows that it is a valid key record. On the other hand, it only shows that it is a record. (It does not crosscheck real signature hashes on real emails that are verified by Zoho.)

On my end, I cannot start using DKIM signatures since Mail Admin > Org > DomainKeys validation have always failed. I don't know why it always fails. Everything looks right.

On the other hand, I consistently get the warning that my MX records are not pointing to Zoho. Well, it is.

Here are some data:

MX:  http://mxtoolbox.com/SuperTool.aspx?action=mx%3amajalmirasol.com&run=toolpage

DKIM:  http://mxtoolbox.com/SuperTool.aspx?action=txt%3adkim._domainkey.majalmirasol.com&run=toolpage

And the screenshot will be at the bottom of the page.

I've just started on using Zoho Mail. And what can I say? It's a great business email with all the features it has. It is just there are a few (advanced) things that must need a little ironing out. I hope that this will be resolved soon for a five/five stars to you!

All the Best,
