POP3 using HTTP Proxy

Demonstrates how to communicate with a POP3 server through an HTTP proxy. .NET Core C#

bool success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The mailman object is used for receiving (POP3) 
// and sending (SMTP) email.
Chilkat.MailMan mailman = new Chilkat.MailMan();

// To connect through an HTTP proxy, set the HttpProxyHostname
// and HttpProxyPort properties to the hostname (or IP address)
// and port of the HTTP proxy.  Typical port numbers used by
// HTTP proxy servers are 3128 and 8080.
mailman.HttpProxyHostname = "www.my-http-proxy.com";
mailman.HttpProxyPort = 3128;

// Important:  Your HTTP proxy server must allow non-HTTP
// traffic to pass.  Otherwise this does not work.

// Set the POP3 server's hostname
mailman.MailHost = "pop.example.com";

// Set the POP3 login/password.
mailman.PopUsername = "myLogin";
mailman.PopPassword = "myPassword";

// Copy the all email from the user's POP3 mailbox 
// into a bundle object.  The email remains on the server.
// 
// NOTE: All methods that communicate with a POP3 server
// will automatically connect and authenticate (i.e. login)
// if not already connected.  The connection will remain
// open after the method call returns so that subsequent
// calls do not need to re-establish the connection.
// In this case, the connection is established via the HTTP
// proxy.
Chilkat.EmailBundle bundle = new Chilkat.EmailBundle();
bool keepOnServer = true;
bool headersOnly = false;
// Irrelevent because we are not downloading headers-only
int numBodyLines = 0;
success = mailman.FetchAll(keepOnServer,headersOnly,numBodyLines,bundle);
if (success == false) {
    Debug.WriteLine(mailman.LastErrorText);
    return;
}

Chilkat.Email email = new Chilkat.Email();
int i = 0;
while (i < bundle.MessageCount) {
    bundle.EmailAt(i,email);

    Debug.WriteLine("From: " + email.From);
    Debug.WriteLine("Subject: " + email.Subject);
    i = i + 1;
}

success = mailman.Pop3EndSession();
