Hi,
In my C# Windows form project, I can receieve the mail from the C# code,
however, it's EMPTY in the MAIL FROM:
Would someone give me some advice?
string Data;
byte[] szData;
TcpClient SmtpServ = new TcpClient(ServSMTP.Text,25);
NetworkStream NetStrm = SmtpServ.GetStream();
StreamReader RdStrm= new StreamReader(SmtpServ.GetStream());
Data = "RCPT TO: " + "<" + txtTo.Text + ">" + CRLF;
szData = System.Text.Encoding.Default.GetBytes(Data.ToCharA rray());
NetStrm.Write(szData,0,szData.Length);
Thanks for help!

With what you have posted, why would you expect to.
That looks like incomplete code for an SMTP Client, not an SMTP Server.

SMTP session
S: greeting text
C: EHLO
S: OK
C: mail from: <>
S: response
C: RCPT TO:: <>
S: response
C: data
S: response
C: sends data
S: response
C: quit
S: response
Thas normal smtp sessiosn what you must follow, most server won't allow RCPT
TO: before all steps before it done.
Probably for you is to use some smtp client.

Hi,
most probably you are not implementing the protocol correctly,
My suggestions are:
1- Simple use the class provided by the framework
2- Download some free smtp client from the net
