Zig Requires Chilkat v11.0.0+

SOCKS4, SOCKS5 Proxy for POP3

Demonstrates how to communicate with a POP3 server through a SOCKS4 or SOCKS5 proxy. Zig

    // This example requires 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.
    const mailman = try chilkat.MailMan.init();

    // To use a SOCKS4 or SOCKS5 proxy, simply set the following
    // properties prior to making any calls that communicate with
    // a POP3 server:
    // The SOCKS hostname may be a domain name or
    // IP address:
    mailman.setSocksHostname("www.mysocksproxyserver.com");
    mailman.setSocksPort(1080);
    mailman.setSocksUsername("myProxyLogin");
    mailman.setSocksPassword("myProxyPassword");
    // Set the SOCKS version to 4 or 5 based on the version
    // of the SOCKS proxy server:
    mailman.setSocksVersion(5);
    // Note: SOCKS4 servers only support usernames without passwords.
    // SOCKS5 servers support full login/password authentication.

    // Set the POP3 server's hostname
    mailman.setMailHost("pop.example.com");

    // Set the POP3 login/password.
    mailman.setPopUsername("myLogin");
    mailman.setPopPassword("myPassword");

    // Copy the all email from the user's POP3 mailbox
    // into a bundle object.  The email remains on the server.
