How to configure a mail server with “docker-mailserver”?


In the next step, you need to make sure that your server’s DNS service uses an MX record for the hostname configured in step 2 (here: “mail-server-docker”). In addition, you have to add a SPF-TXT record with hostname and value “v=spf1 mx ~all”.

As an IONOS customer, you can also perform these DNS settings for your server via the Cloud Panel by doing the following:

  1. Log in again on the Cloud Panel login pageif you are no longer logged in.
  2. Click on the entry ” Domains and SSL “.
  3. Tap the gear icon near the entry for the domain you are setting up your mail server on and select the option ” DNS “.
  4. By clicking on the button ” Add record you can now add the two entries for MX and SPF-TXT.
