I believe yes. The A mail record should contain the IP address of your e-mail/hosting provider (maybe it should be the same as
22.214.171.124 and not
126.96.36.199 - if this one is your IPv4 address from home network or I am wrong and this IP address is actually from your e-mail server/hosting?).
Try leaving the value as is “dc-…” and check later if you can send/receive e-mails.
Of course, at your e-mail client (like Outlook or Thunderbird, or some other) for “incomming/outgoing server” use the hostname
From the screenshot above, I am just not 100% aware if a MX record for your domain points to a good location? - I have not used a lot “hostnames” like “dc-something.domain…”.
Due to most situations the MX record under “content” has got a value like
mail.yourdomain.com (priority either 0 or 10).
Also, from the provided screenshot, kindly to make sure you can connect to your FTP (either using FileZilla or some other FTP client), this one record should also be cloud (DNS only) - so, just click on the near FTP to be it .
That is the right way, yes.
Now when I check I see Cloudflare nameservers as a response (if not yet, will be in few hours due to the DNS propagation):
retetefaragluten.ro. IN NS
retetefaragluten.ro. 21599 IN NS dawn.ns.cloudflare.com.
