Visual C++ Example

SSL connection encrypts data between the email component and POP3 server or IMAP4 server to protect user, password and email content in TCP/IP level. Now this technology is commonly used and many email servers are deployed with SSL such as Gmail, Yahoo and Hotmail. There are two ways to deploy SSL on email server: 1. Using STARTTLS or STLS command to switch SSL channel on normal port (POP3: 110 or IMAP4: 143); 2. Deploying SSL on another port (POP3: 995 or IMAP4: 993 you may query it from your server administrator) directly.

The following example codes demonstrate how to retrieve email over SSL connection from IMAP4 server. This sample downloads emails from IMAP4 server and deletes the email after the email is retrieved.

Code:

// The following example codes demonstrate retrieving email over SSL connection from IMAP4 server
// To get full sample projects, please download and install EAGetMail on your machine.
// To run it correctly, please change email server, user, password, folder, file name value to yours
