I try connect to server "smtp.mail.ru" with proxy. Proxy type is socks5 with auth. Its show error
"Limilabs.Proxy.Exceptions.ProxyException: "Proxy authentification failure."
My code:
ProxyFactory factory = new ProxyFactory();
IProxyClient proxy = factory.CreateProxy(
ProxyType.Socks5,
proxyServer,
proxyPort,
proxyUser,
proxyPass);
var server = "smtp.mail.ru";
var socket = proxy.Connect(server, 467);
Proxy worked. c# http get request with this proxy worked good.
