Received mysterious "immediate action required" email from Zoho: Legitimate, or Spam?

Received mysterious "immediate action required" email from Zoho: Legitimate, or Spam?

I have received an email purporting to be from Zoho, with the subject line WARNING::Need Immediate Action and the following body text:

"Dear (my Zoho email addy),

Problem while forwarding mails to (my designated forwarding email addy). Repeated failure will disable email-forwarding.

Regards,
Zoho Mail Mail Administration

This is an automated message, please do not reply"

However, all emails that have arrived in my Zoho inbox have indeed been forwarded as usual. And what "immediate action" am I supposed to be taking??  This looks and sounds very fishy to me. Please advise if this is indeed from Zoho, and if it is, why it was sent and what if anything it is asking me to do. Thanks!
