Hello,
I did follow the tutorials and set the MX record as directed (I hope). but still can’t connect
it should be noted that mails are accessible on webmail, only outlook and mobile devices cant connect using POP3 or IMAP.
my domain is cdc-cameroon.com
Regards.

Sorry, assuming you are using the naked domain or mail.domain.com you didn’t.

Unproxy :grey: the DNS record which is responsible for mail handling. Step four in the linked atricle you followed.

nslookup mail.cdc-cameroon.com                         Server:127.0.0.53
Address:127.0.0.53#53
