Dear XXXX,

Problem while forwarding mails to XXXX@me.com. Repeated failure will disable email-forwarding.

Regards,

Zoho Mail Mail Administration

However all emails seem to be forwarding, and I don't know what the actual error is, and not sure what action I need to take.  This is a bit annoying only in that it has routinely stopped disabled forwarding for no apparent reason.

This seems to be mostly effecting redirection to iCloud addresses.
