(C#) SMTP using SOCKS5, SOCKS4 ProxyDemonstrates how to communicate with an SMTP server via a SOCKS4 or SOCKS5 proxy.
// 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. Chilkat.MailMan mailman = new Chilkat.MailMan(); // 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.SocksHostname = "www.mysocksproxyserver.com"; mailman.SocksPort = 1080; mailman.SocksUsername = "myProxyLogin"; mailman.SocksPassword = "myProxyPassword"; // Set the SOCKS version to 4 or 5 based on the version // of the SOCKS proxy server: mailman.SocksVersion = 5; // Note: SOCKS4 servers only support usernames without passwords. // SOCKS5 servers support full login/password authentication. // Set the SMTP server. mailman.SmtpHost = "smtp.chilkatsoft.com"; // Set the SMTP login/password (if required) mailman.SmtpUsername = "myUsername"; mailman.SmtpPassword = "myPassword"; // Create a new email object Chilkat.Email email = new Chilkat.Email(); email.Subject = "This is a test"; email.Body = "This is a test"; email.From = "Chilkat Support <support@chilkatsoft.com>"; bool 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) { Debug.WriteLine(mailman.LastErrorText); 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) { Debug.WriteLine("Connection to SMTP server not closed cleanly."); } Debug.WriteLine("Mail Sent!"); |
