Using SSL for HTTPS, SMTP, POP3 and IMAP

An SSL certificate is required before you can enable and use SSL for SMTP, POP3 and IMAP protocols. This article talks about different options for obtaining an SSL certificate.

Option 1 - obtaining a free SSL certificate from Let's Encrypt Recommended

Let's Encrypt is an open certificate authority that issues SSL certificates for free. Click here to watch a short video demonstrating the steps you need to take in order to get a free certificate that is trusted by most modern browsers.

Option 2 - using a self-signed certificate

Simply change the value for Secure Web Server Port under Server Configuration and restart Xeams. Xeams will automatically download a self-signed certificate from Synametrics' Website. This certificate will NOT be trusted by any browser. This method should only be used for testing or non-production Xeams.
