Socks5 authentication failure

Question

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.

Answer 1

1. Are you sure 467 port is correct?
   Port 465 is used for SMTP over SSL/TLS.
2. This error simply means that server refuses your credentials.
3. You can create a test account and provide credentials using the email in the footer if you want us to analyze it further.
