SmtpClient.Quit Method


Disconnects the smtp server.

[Visual Basic]
Public Sub Quit( _
)
[C#]
public void Quit(
);
[C++]
public: void Quit(
);
[JScript]
public function Quit(
);

Remarks

The combination of Connect, Quit, Reset methods and SmtpClient.SendMail( SmtpMail mail ) methods sends multiple emails in one SMTP connection session. DO NOT use Connect, Quit and Reset methods with SmtpClient.SendMail( SmtpServer server, SmtpMail mail ) method. SmtpClient.SendMail( SmtpServer server, SmtpMail mail ) method connects and disconnects smtp server automatically.
