Hi,

I've installed Indy 9.0.18 on my C++Builder Professional edition IDE.

I've got some old information (2002 -  2004) on the Internet about
using the TIdSMTP to connect to the Gmail SMTP server which
requires SSL authentication.

I put the code bellow in the IdSMTP::OnConnected event hendler :
[code]
void __fastcall TForm1::SMTPConnected(TObject *Sender)
{
  SMTP->SendCmd("STARTTLS", 220); // jjf Applications hungs here
  SSLHandler->PassThrough = false;
  SMTP->Authenticate();
}
[/code]

If I comment the line {SMTP->SendCmd("STARTTLS", 220); } the application
execute the Authenticate method and there is no any Exception, otherwise the
application freezes !

Is the Indy 9 TIdSMTP component able to perform an SSL connection or not ?
Or it doesn't work with C++Builder and just with Delphi ?

Thanks a lot.

Do NOT send any SMTP commands in the OnConnected event hander.
TIdSMTP::Connect() performs various commands after connecting to the server,
namely processing the server's Greeting text and then requesting the
server's capabilities.  However, the OnConnected event is triggered before
that processing occurs.  If you send your own commands from inside the
OnConnected event, you will corrupt the conversation that TIdSMTP has with
the server.  You must wait until Connect() fully exits before doing
anything.

I suggest you upgrade to Indy 10.  TIdSMTP in Indy 10 has native support for
the STARTTLS command.

Hi Remy,

As far as I know Indy 10 do not work with C++Builder6.0 , am I right ?

TIA

 From reading Remy's replies to other posters asking the same 
question...it can't be done as it is not currently supported.
