SMTP using SOCKS5, SOCKS4 Proxy

Demonstrates how to communicate with an SMTP server via a SOCKS4 or SOCKS5 proxy. Go

    success := false

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

    // The mailman object is used for sending and receiving email.
    mailman := chilkat.NewMailMan()

    // To use a SOCKS4 or SOCKS5 proxy, simply set the following
    // properties prior to making any calls that communicate with
    // an SMTP 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 SMTP server.
    mailman.SetSmtpHost("smtp.chilkatsoft.com")

    // Set the SMTP login/password (if required)
    mailman.SetSmtpUsername("myUsername")
    mailman.SetSmtpPassword("myPassword")

    // Create a new email object
    email := chilkat.NewEmail()

    email.SetSubject("This is a test")
    email.SetBody("This is a test")
    email.SetFrom("Chilkat Support <support@chilkatsoft.com>")
    success = email.AddTo("Chilkat Admin","admin@chilkatsoft.com")

    // Call SendEmail to connect to the SMTP server and send.
    // The connection (i.e. session) to the SMTP server remains
    // open so that subsequent SendEmail calls may use the
    // same connection.  
    success = mailman.SendEmail(email)
    if success != true {
        fmt.Println(mailman.LastErrorText())
        mailman.DisposeMailMan()
        email.DisposeEmail()
        return
    }

    // Some SMTP servers do not actually send the email until 
    // the connection is closed.  In these cases, it is necessary to
    // call CloseSmtpConnection for the mail to be  sent.  
    // Most SMTP servers send the email immediately, and it is 
    // not required to close the connection.  We'll close it here
    // for the example:
    success = mailman.CloseSmtpConnection()
    if success != true {
        fmt.Println("Connection to SMTP server not closed cleanly.")
    }

    fmt.Println("Mail Sent!")

    mailman.DisposeMailMan()
    email.DisposeEmail()
