Actually when I read about this functionality on the previous implementations, I see that it is close to what we are doing. When I look the packages from Wireshark, I see that when we do not send any QUIT message to server, we close the connection in the middle and as I know if that happens Smtp server should skip this mail request. Am I right?
I wouldn't be surprised if there are servers who would send it off anyway, but the SMTP spec in RFC 2821 section 4.1.1.10 for QUIT is quite clear:
The sender MUST NOT intentionally close the transmission channel until it sends a QUIT command and SHOULD wait until it receives the reply (even if there was an error response to a previous command). If the connection is closed prematurely due to violations of the above or system or network failure, the server MUST cancel any pending transaction -- / daniel.haxx.se ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
