Question

How to configure domain DNS records to use Plesk as mail server?

Answer

Corresponding MX records should be configured on the registrar side.

For domain example.com the following records should exist:

1. MX record for domain example.com which point to the mail server, for example mail.example.com:

   Type: MX
   Host: example.com
   Value: mail.example.com
   Priority: 0.

2. A record for the domain used in the MX record, which points to the server with Plesk:

   Type: A
   Host: mail.example.com
   Value: 203.0.113.2

Note: these DNS records should be configured on the registrar side according to its documentation. Contact the registrar for assistance.
