The SMTP protocol doesn't directly support HTTP proxy. You need to add an additional component, TclHttpProxy, and assign the TclSmtp.Proxy property with an instance of this component. Other TCP-based client components (TclImap4, TclPop3, TclSFtp, etc.) are configured in the same way.

 

private void btnSMPT_Click(object sender, EventArgs e)
{
	httpProxy1.UserName = "user";
	httpProxy1.Password = "psw";
	httpProxy1.Server = "proxy-domain.com";
	httpProxy1.Port = 8080;

	smtp1.Proxy = httpProxy1;

	smtp1.UserName ="mail-user";
	smtp1.Password = "secret";
	smtp1.Server = "mail-host";
	smtp1.Port = 25;
	smtp1.Open();
}
