Cannot send email (via GMail) with Indy. Protocol version mismatch - email

Question

I want to send an email via GMail server.
TRY
SMTP.Connect; // <---- This is TIdSMTP
EXCEPT
Log.AddError('Cannot connect to the email server.');
END;
if SMTP.Connected then
TRY
SMTP.Send(MailMessage);
EXCEPT
on E:Exception DO
begin
Log.AddError('Connected to server but could not send email!');
Log.AddError(E.Message);
end;
END;
if SMTP.Connected
then SMTP.Disconnect;
This piece of code worked in 2014 with Delphi XE.
The program connects to the server ok but in the end it says "SSL is not available on this server":
Resolving hostname smtp.Gmail.com.
Connecting to 74.125.xxx.xxx
Connected.
Connected to SMTP server...
SSL status: "before/connect initialization"
SSL status: "before/connect initialization"
SSL status: "SSLv3 write client hello A"
SSL status: "SSLv3 read server hello A"
SSL status: "SSLv3 read server hello A"
Disconnected.
Connected to server but could not send email!
SSL is not available on this server.
I have the latest version of OpenSSL (downloaded today) and Delphi XE7.
The WireShark says:
Alert (Level: Fatal, Description: Protocol version)
Why I cannot send email?
I have tried all: no TSL, implicit, explicit, startTSL...

Answer 1

SOLUTION: sslvTLSv1 must be included in the SSLIOHandler.SSLVersions property.
