Uso questa procedura generale per inviare e-mail. Supporta anche gli allegati (solo testo normale) e le e-mail non sono limitate a 32767 caratteri.
Se non hai affatto bisogno di allegati, non dovrebbe essere un problema rimuoverli.

Linee. Sembrano ridondanti, tuttavia la maggior parte è richiesta! Anche un messaggio di cortesia come "Questo è un messaggio in più parti in formato MIME". è necessario per una corretta visualizzazione della posta in caso di allegati.
Se riscontri ancora problemi, crea un dbms_output.put_line(ret.code||': '||ret.text);
dopo ogni chiamata di funzione su UTL_SMTP.
