Removing a domain from Zoho Mail grey list

Removing a domain from Zoho Mail grey list

Hello there, Could you please check and remove the domain "x-pressfeeders.com.lk" from your grey list as one of my clients is not receiving emails sent from this domain? This is nothing to do with my client's email box or email client settings as all emails from this domain are rejected by mx.zoho.com. Best regards,
