SSL certificate setup for pop3s, imaps, smtps on Plesk

Posted on November 19, 2010

For Parallels Plesk Panel version 9, 10, 11:

Settings -> SSL Certificates -> Add SSL Certificate

Fill in required preferences and click button {Self-Signed}

New self-signed SSL certificate will be created in server certificate repository.

To assign this SSL certificate for securing your Parallels Plesk Panel mark enabled new SSL certificate in the list and push Secure control panel if you have Plesk 8.2 or later, or Install if you have older Plesk version.
Also, see Plesk documentation how to setup self-signed certificates.

After you created or uploaded new certificate into Plesk and wish to use it for domains you should set it for every IP you need, so domains use it when you access them via HTTPS.
It can be done on page Server -> IP Addresses -> “choose IP” by selecting needed Certificate in “SSL Certificate” drop down menu.

or

I use 1 SSL cert for plesk control-panel, pop3s, imaps and smtps.

After generating the new certificate in the administrator repository. make it your default certificate and mark it again and press setup to install it on your plesk admin server on port 8443. then put the certificate at your main ip-adresse in your ip-pool(maybee this step is not necessary).

copy /usr/local/psa/admin/conf/httpsd.pem
to
/usr/share/courier-imap/pop3d.pem, /usr/share/courier-imap/imapd.pem and /var/qmail/control/servercert.pem

please have a look that the owner(very important) and the chmod rights are the same of pop3d.pem, imapd.pem and servercert.pem. like before otherwhise qmail will for example not work/start, because it can’t read the file.

restart courier(imap,pop3) and qmail(smtp) in the plesk server service control panel.

after this plesk control-panel 8443, pop3s, imaps and smtps should work without warning messages and with only 1 ssl cert, if you use for all services the same main hostname.domain.com address like me.

(You should also double check that your hostname is configured in the qMAIL config)

Now test your certificates:
