Understanding SSL email connections

When I set up an IMAP email account in one of my cPanel accounts, a "Mail Client Manual Settings" email is generated. This recommends IMAP Port 993 for the incoming server and incoming server and SMTP Port 465 for the outgoing server for "Secure SSL/TLS Settings (Recommended)". When I set up to connect that account with Apple Mail, it automatically sets up the account as you would expect, but when I go into advanced settings, even though the "Use TLS/SSL" checkbox is checked for both the incoming and outgoing servers, the ports are set per the "Non-SSL Settings (Not Recommended)" settings in the Mail Client email generated when I set up the email account in cPanel. My question is: If I leave the port settings as Apple Mail sets them (143 incoming and 587 outgoing) will I still have secure (encrypted) email connection to the server, or must I manually change them to the recommended 993 and 465? I'm not sure why Apple mail sets the ports to the "Non-Secure" settings even though "Use TLS/SSL" is checked. I'm just needing to know if I need to tell people using Apple Mail to manually change their port settings to 993, 465, if they want secure SSL email connections?

  You can use secure port 465 or 587 for outgoing server ( remember to open the ports in firewall) But 143 is not secure so use 993 for incoming.

  993 is secure and 143 is not - you can use the configuration tool to have them automatically set up as well.
