You missed out the “Expert Settings” options but I have found the SSL Accounts page

I only have SMTP listed for BT Connect not POP3 and I can add it as there is one for O2 POP3 with encryption set to none

However the heading of this table says that entries are not needed for non SSL connections which does not make sense as this indicates one for BT Connect should not be needed but then neither is the one for O2.
