Rust Requires Chilkat v11.0.0+

POP3 using HTTP Proxy

Demonstrates how to communicate with a POP3 server through an HTTP proxy. Rust

// 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.
let mailman = chilkat::MailMan::new();

// 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.set_http_proxy_hostname("www.my-http-proxy.com");
mailman.set_http_proxy_port(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.set_mail_host("pop.example.com");

// Set the POP3 login/password.
mailman.set_pop_username("myLogin");
mailman.set_pop_password("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.
let bundle = chilkat::EmailBundle::new();
let keep_on_server = true;
let headers_only = false;
// Irrelevent because we are not downloading headers-only
let num_body_lines = 0;
if mailman.fetch_all(keep_on_server, headers_only, num_body_lines, &bundle).is_err() {
    println!("{}", mailman.last_error_text());
    return;
}

let email = chilkat::Email::new();
let mut i = 0;
while i < bundle.message_count() {
    let _ = bundle.email_at(i, &email);

    println!("From: {}", email.from());
    println!("Subject: {}", email.subject());
    i = i + 1;
}

let _ = mailman.pop3_end_session().is_ok();
