Urgent Register.com Email Fix

Job ID: 39909600

Budget: $10 – $12 USD

My email has stopped not working - I can't receive or send emails
It is a domain based email hosted along with my website at register.com
I haven't changed anything in hosting
Need you to quickly check & it to restore it (Inspect: DNS zone files/IMAP/MX/SPF/DKIM)
Thanks
