Zoho mail stopped working on Saturday 5/2
We have not received any email with any of our 8 users since 5/2. They can send out just fine, but nothing is received. This is true using our thunderbird email clients, our iphones, and zoho web-based email. When test emails are sent to any of the 8 user accounts from outside the domain, they are simply not received. No error messages, no bounces, nothing. Any help would be greatly appreciated.
