System.Net.Mail SmtpClient SMTP Quit Command

[Guest]

I am using System.Net.Mail for sending mail.

How do I force a SMTP Quit command (SMTP session termination) with the
SmtpClient class ?

Even when the SmtpClient object goes out of scope and I reinstantiate the
SmtpClient class the SMTP session appears to not be terminated. What causes
SMTP session start-up and shutdown with the System.Net.Mail SMTPClient class ?

Thanks

Hello,

IMHO, this is major implementation flaw in the current SMTPClient. The
SMTPClient uses the ServicePointManager internally to cache connections, so
it doesn't send a QUIT command. I don't know if one can gracefully close
such servicepoint instance.

Kind regards,

Check the SMTP client class in SecureBlackbox (see http://www.eldos.com/sbb/net-mime.php
for details)
