Email configuration using SSL on port 465 timing out when testing email setup

After setting correct SMTP email configuration to use SSL on port 465, the testing times out and does not send emails.

The software uses System.Net.Mail for outgoing emails. This only supports "explicit SSL" and will fail if your SMTP is set to use SSL on port 465.

Please use TLS/STARTTLS on port 587 instead if possible (you still need to select the "Mail Server Requires SSL" YES).
