I noticed DirectAdmin supports TLS SNI for imap/smtp with Let's Encrypt on their latest release. I've test it and it works really nice. But I'm more of a ISPconfig person then DirectAdmin. I'm curious: is it already possible to support TLS SNI for Postfix/Dovecot with Let's Encrypt on ISPconfig3? If not: are their any plans to implement this? The end result is you can host multiple domains on 1 IP-address and not only do https: for every domain, but also present a valid Let's Encrypt-certificate for mail-connections (pop/imap & smtp). Running Ubuntu 16.04 (Xenial) and ISPConfig Version: 3.1.8p1. Thanks!
