My setup: VPS in datacenter The perfect server - Ubuntu 10.04 ISPConfig 18.104.22.168 (updated) POP3/IMAP Daemon: Courier Mailfilter Syntax: Maildrop Webmail client: Squirrelmail Certificate by StartCom Ltd. used for ISPConfig (server IP address/FQDN). Works perfectly. 4 websites are hosted by this server. Now I want the email addresses that belong to these sites to be secure with use of SSL. What must I do to achieve this?
