I can not seem to find anything about the SSL features for the web client. By default I see a normal connection on port 80 to the server. This would mean any traffic regarding credentials and maybe more is unencrypted? What steps should be taken to enable a SSL connection?
Besides this, I see in the master.cf configuration of postfix that SSL for smtp is on by default. I am correct that all of the credentials sended out by a mail client trough a SMTP secure port is encrypted? I have opened port 465 on my firewall for this, is that correct?
