I have a web server hosting multiple domains (centos + postfix + dovcot), one of my domain its dns is hosted on cloudflare (ie. abcd.com), but when I use gmail to send email to a [email protected], [email protected] will not be able to receive the email. Here is the MX record I set in cloudflare:
Type Name Value TTL Active mx mail handled by mail.abcd.com with priority10 Automatic cname mail is an alias of abcd.com Automatic grey cloud
Any knows how can I make the domain receive the emails?
You have two distinct errors in your configuration:
The MX record should be for your domain, not for a subdomain.
An MX record should not point to a CNAME. Point it to a record with an IP address.
