It's telling you that you sending a bad request.... First off.. That zero char at the end of your headers is not needed....  Second, you don't send null terminated strings to the server... That is why you give send a length. Minus the null.   So you are sending noauth and telling send it is 3 bytes... It is only 2

zNOAUTH db 5h, 1h, 0h
szCONNECT db 5, 1, 0, 3, 14, 'smtp.yandex.ru', 0, 25, 0

5H, 1h, 5, 1, and ,0 are control characters... Sending them to a server is a good way to get your ip blocked from using the server... Be careful what you send to a server... If you are trying to send the numbers 5,1, and 0.... Enclose them in quotes...

[bomz]

Try without 0

the answer from server


May be request must be modificate or something else must be send to proxy after authorization and connect request which not in rfc

[bomz]

you was partially wright

   szCONNECT      db 5, 1, 0, 3, 14, 'smtp.yandex.ru', 0, 25;, 0

This NULL was excess

somebody knows how with HTTP proxy work? Please help
with socks5 also workin not very correct sometimes application begin use 100% of processor

How to Do This

Now, it's your program's turn to fool the proxy server and behave as Internet Explorer behaves for Secure HTTP.

   1. Connect to Proxy Server first.
   2. Issue CONNECT Host:Port HTTP/1.1<CR><LF>.
   3. Issue <CR><LF>.
   4. Wait for a line of response. If it contains HTTP/1.X 200, the connection is successful.
   5. Read further lines of response until you receive an empty line.
   6. Now, you are connected to the outside world through a proxy. Do any data exchange you want.
