DNS Configuration

To receive emails for your domain, configure DNS records:

A Record

Point your mail subdomain to your server IP:

A    mx    YOUR.SERVER.IP.ADDRESS

MX Record

Configure MX record to route emails to your server:

MX   *    mx.yourdomain.com

The * wildcard means ALL subdomains will be routed to your server. Examples: test@yourdomain.com, anything@sub.yourdomain.com This gives you unlimited email addresses!
