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 firstname.lastname@example.org, email@example.com 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?
