oooooh man.

Delphi-Quellcode:

procedure TForm1.btnEinloggenClick(Sender: TObject);
var
  slText: TStrings;
  s: String;
begin
  s := '[e-mail]';
  IdSMTP1.Host := 'smtpmail.t-online.de';
  IdSMTP1.Username := '[e-mail]';
  IdSMTP1.Password := 'Password';

  IdPOP31.Host := 'popmail.t-online.de';
  IdPOP31.Username := '[e-mail]';
  IdPOP31.Password := 'Password';

  IdMessage1.Sender.Name := '[e-mail]';
  IdMessage1.Sender.Address := '[e-mail]';
  IdMessage1.From.Text := '[e-mail]';
  IdMessage1.Sender.Text := '[e-mail]';

  with IdMessage1.Recipients.Add do
    begin
      Name := PChar('');
      Address := PChar(s);
    end;

  IdMessage1.Subject := 'Hallo Ich';

  slText := TSTringList.Create;
  slText.Add('Hier werden die Daten später stehen');

  IdMessage1.Body := slText;

  IdPOP31.Connect;
  try
    IDSMTP1.SendMsg(IdMessage1);
  finally
    IdPOP31.Disconnect();
  end;
  slText.Free;
end;

Springt mir bei IdPOP31.Connect raus und meint Ivalid Login
