gmail SMTP

Im build a C++ programa where i access gmail SMTP by SSL, then all set up, authenticated and everything, i start writing my message, but, what should i do in order to the SMTP server know that the message has achieved it´s end? i tried to use "\n.\n" at the end but no answer came up. Thank you in advance

AH! And i almost forgot, does the message have to be MIME?

Just trace it with ethereal using your regular client.
Then make your program do the same things.

can i trace it even if its comunication is made by ssl?

Never mind.

I got some errors when starting the trace or sometimes when stoping it. Windows XP Professional SP2

Ok, i got it working but as i expected the packets aren´t readable. Any idea?

Got it. According to RFC 2821 the end of the email should be specified by "\r\n.\r\n"
