How to add a Plesk email account in an email client using the local mail server's SSL certificate

Question

How to add a Plesk email account in an email client (Outlook, Thunderbird, Apple Mail, etc.) using the local mail server's SSL certificate?

Answer

Note: The recommended way to set up email accounts over a secure connection is to use domain's SSL certificate. For more information, refer to this KB article.

1. Log in to Plesk.

2. Make sure a valid SSL certificate is assigned to the mail server in Plesk at Tools & Settings > SSL/TLS Certificates and domain's name in the certificate is the same as the name of Mail server.

   
   
    

3. Click on the certificate name to find out for which domain name it was issued.

   
   
    

4. When a valid SSL certificate is set up for a mail server and domain name is known, during configuration in a mail client, specify incoming and outgoing mail server name as domain name from step 2.
   • Incoming server
     • IMAP - use port 993 with SSL type.
     • POP3 - use port 995 and enable the option This server requires an encrypted connection (SSL), if available.
   • Outgoing server (SMTP) to use port 465 (or 587 if the submission port is enabled) with SSL or TLS type (depends on the server configuration).
