Delphi Example
Yahoo POP3 server address is "pop.mail.yahoo.com" or "plus.pop.mail.yahoo.com". It requires SSL connection on 995 port, and you should use your Yahoo email address as the user name for user authentication. For example: your email is "myid@yahoo.com", and then the user name should be "myid@yahoo.com".

The following example codes demonstrate how to retrieve email from Yahoo POP3 server.
