Is it possible to secure the mail server mail.example.com with Let's Encrypt SSL certificate when the A record for example.com is pointing to another server?

Answer

Yes, after you update Plesk to version 18.0.71, you may achieve this easily by following these steps:

1. Log into Plesk

2. Navigate to Domains > example.com > Hosting Settings

3. Go to Domains > example.com > SSL/TLS Certificates

4. Issue a Let's Encrypt SSL certificate for example.com by making sure the only the Secure mail on this domain and Assign the certificate to the mail domain options are checked

5. Press Get it free

  • Is this a joke? This makes no sense!

    That means we can't sell 'email only' accounts?!

    I have one client right now in this situation, and Plesk has created a huge problem for them.

  • As Plesk is unable to fix this behaviour for years now I've made a small Script which works around the issue - hope it helps ya all! ;-)

  • I host hundreds of domains across multiple servers. It’s impractical to monitor when a mail.example.com certificate will renew and manually reassign it—it’s absurd. Please fix this. When a certificate auto-renews and is assigned to mail services, it should be reassigned automatically to avoid client alerts.

  • There is a missing step after Step 2. After you go to Hosting settings, you need to set the Hosting type to “No web hosting”. Only then will you be able to issue certs for the mail domain only.
