[twsocket] SmtpClient problem on disconnect

[David A. G.]

Hello all:

I'm having problems SmtpCli where OnRequestDone function is not fired after 
sending QUIT command because the SMTP server is not closing the 
connection!!. It occurs only when using EHLO command and AUTH LOGIN 
authentication. I have tryed with 2 servers with same results (big linux 
servers).

To solve that, I have changed SmtpProt.pas:

FROM:

procedure TCustomSmtpClient.NextExecAsync;
...
...
    if Assigned(FDoneAsync) then
        FDoneAsync
    else if (FRequestType <> smtpQuit) or (FConnected = FALSE) then
        TriggerRequestDone(FRequestResult)
    else begin
        { We have to wait until remote host close connection before  }
        { calling TriggerRequestDone. See WSocketSessionClosed. }
    end;
end;


TO:

procedure TCustomSmtpClient.NextExecAsync;
...
...
    if Assigned(FDoneAsync) then
        FDoneAsync
    else
        TriggerRequestDone(FRequestResult)
    end;
end;
...then in the OnRequestDone I can close connection (if necessary) by 
calling CloseDelayed.


any idea??

thanks in advance,
David
