跪求INDY10中idpop3和IdSSLIOHandlerSocketOpenSSL使用SSL连接Gmail用法,该怎么解决

跪求INDY10中idpop3和IdSSLIOHandlerSocketOpenSSL使用SSL连接Gmail用法
郁闷3天了, 就是不知道咋弄,网上该搜的都搜索了.

// 指定新邮件的地址等信息
IdSSLIOHandlerSocketOpenSSL1->SSLOptions->Method = sslvTLSv1;
//IdSSLIOHandlerSocketOpenSSL1->Destination = "pop.gmail.com:995";
// IdSSLIOHandlerSocketOpenSSL1->SSLOptions->Mode = sslmClient;
//IdSSLIOHandlerSocketOpenSSL1->SSLOptions->VerifyDepth = 0;
//IdSSLIOHandlerSocketOpenSSL1->RecvBufferSize = 1024;
IdSSLIOHandlerSocketOpenSSL1->Host = "pop.gmail.com";
// IdSSLIOHandlerSocketOpenSSL1->Port = 995;

POP->Host = "pop.gmail.com";
POP->Port = "995"
POP->Username = "username";
POP->Password = "password";
POP->UseTLS = utNoTLSSupport;
POP->IOHandler = IdSSLIOHandlerSocketOpenSSL1;
POP->ConnectTimeout = 10000;
try
{
POP->Connect();
}
catch( EIdException &e )
{
Memo1->Lines->Add("连接错误: " + e.Message);
}

结果是:  
连接状态:Connected.
连接中...
连接错误: Connection Closed Gracefully.

每次都是Connection Closed Gracefully. 怎样设置属性啊??是否需要SSL证书才能连接?只有98分,全送了.

Indy10的具体版本号是多少?

我是用Delphi测试的:

var
popMsg: TIdPOP3;
sslConn: TIdSSLIOHandlerSocketOpenSSL;
begin
sslConn := TIdSSLIOHandlerSocketOpenSSL.Create(Nil);
try
popMsg := TIdPOP3.Create(Nil);
try
popMsg.IOHandler := sslConn;
popMsg.Host := 'pop.gmail.com';
popMsg.Port := 995;
popMsg.Username := 'MyGMailUserName@gmail.com';
popMsg.Password := '********';
popMsg.UseTLS := utUseImplicitTLS;
popMsg.Connect;
ShowMessage('MessageCount:'+IntToStr(popMsg.CheckMessages));
finally
popMsg.Free;
end;
finally
sslConn.Free;
end;
end;
