Broken domain

We are experiencing significant issues with our email system, specifically concerning our domain email address, which has rendered Google Mail inoperable. As a result, we urgently require assistance to restore functionality to our office emails. We seek a skilled professional with expertise in email configuration and domain management to diagnose and resolve these issues promptly. Your prompt attention to this matter will be greatly appreciated, as we rely heavily on our email communications for daily operations. Please submit your proposals for consideration.
