Hi,

Wow, that was fast Oblivion! Thanks!!

However, sending with STARTTLS failed with an error:

503 5.5.1 Error: send HELO/EHLO first

when processing:

String ans = SendRecv("AUTH LOGIN\r\n");

I fixed it by removing the 'else' after initializing STARTTLS and allowing new HELO inside STARTTLS mode. I think I read somewhere that after going into STARTTLS makes server drop all prior information and therefore requires starting over with new HELO:

	throw Exc("Server does not provide SMTP service information.");
}
//else
	SendRecvOK("HELO " + org + "\r\n");
if(!IsNull(auth_user)) {
	String ans = SendRecv("AUTH LOGIN\r\n");
...

Can you confirm if this is correct? It seems to work fine on my ISP's SMTP server.

Thanks and best regards,

Tom
