I need to send the email with the .ics file attached. The ics-file is generated correctly. There is no error but I don't receive the mail. How can he knows the password of the account  from where I'm sending the mail?? Can someone help?

createTextFile(this, "BEGIN:VCALENDAR
VERSION:2.0
CALSCALE:GREGORIAN
BEGIN:VEVENT
UID:event-" + Evento + 'Nr. persone' + "persone" + ".ics
SUMMARY:" + 'Fase di' + Evento.Evento + "

STATUS:CONFIRMED
END:VEVENT
END:VCALENDAR", "event-" + Evento + ".ics");
"Ask the user to confirm sending of confirmation";
"(this allows time for the file to be created)";
"-----------------------------------------------";
let result := dialog("Invio evento", "Devo aggiungere " + 'Fase di' + " " + Evento.Evento + "  al calendario?", ["Si", "No"]);
if result = "Si" then
let filetosend := file(this, "event-" + Evento + ".ics");
let emailText := "Dear Walcher Messebau, This is a confirmation of your booking for " + Evento.Evento + "</b><br>Starting: <b>" + Evento.'Inizio evento' + "</b><br>Ending: <b>" + Evento.'Fine evento' + "</b><br><br>" + Evento.Evento + "
