VB6 - Retrieve Email from Yahoo Account

The following vb6 example codes demonstrate how to retrieve email from Yahoo IMAP4 server.

Yahoo POP3 server address is pop.mail.yahoo.com. It requires SSL connection on 995 port; Yahoo IMAP4 server address is imap.mail.yahoo.com . It requires SSL connection on 993 port. 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.

Server Port SSL Protocol
pop.mail.yahoo.com 995 SSL required Pop3
imap.mail.yahoo.com 993 SSL required Imap4
