Salve a tutti, in primis vorrei dire che ho modificato il thread in quanto mi sono accorto di aver dimenticato alcune regole (mea culpa). Ora passo al problema: in sostanza sto creando una specie di gestionale, e mi servirebbe sapere se con la libreria qt4, o con eventualmente una terza libreria, posso inviare delle e-mail attraverso il protocollo smtp. L'email dovrebbe essere inviata con autenticazione.

Vorrei evitare (per il momento) di dovermi studiare i socket e implementare del codice utilizzando direttamente questi, perché è un progetto scolastico che non prevede nella valutazione questo tipo di classi. E' ovvio che comunque è ben accetta qualsiasi tipo di documentazione a riguardo (che mi studierò con un pò più calma in futuro)

EDIT: googlando ho trovato un post (di un forum francese) in cui forse ho trovato la soluzione ai miei problemi (link: http://forum.qtfr.org/viewtopic.php?id=7736 post #16). Riporto il codice:

Uso della classe

  1. MailSender test1(serveur_mail, from,liste_diffusion , "Titre de mon message", message);
  2.                 test1.setPriority(MailSender::high);
  3.                 send(test1)


Ho importato nel progetto i due file, e ho richiamato la funzione in questo modo:
Codice sorgente - presumibilmente C/C++
  1. QString server="smtp.gmail.com", from="prova1@gmail.com", oggetto="ciaooo", messaggio="ciaoo";
  2.     QStringList to;
  3.     to<< "maryano-campa@hotmail.it";
  4.     MailSender test1(server, from, to, oggetto, messaggio);
  5.     test1.send();
