Is Zoho Server Hacked Again
Hi
From last couple of days i have noticed a spike in DMARC Reports coming from Russian Mail Service Provider qq.com. The reports are indicating failure for some in DKIM or Temp Error for SPF BUT all have been sent from server163-mail.zoho.com.
As far as i am aware, none of the users are sending mails to this service provider. Can you confirm if the server has been compromised again ?
