Jag använder denna allmänna procedur för att skicka ut e-post. Den stöder även bilagor (endast vanlig text) och e-postmeddelanden är inte begränsade till 32767 tecken.
Om du inte behöver bilagor alls bör det inte vara några problem för dig att ta bort dem.

Bara en notering, missa inte UTL_SMTP.write_data(con, UTL_TCP.CRLF)
rader. De ser överflödiga ut, men de flesta av dem krävs! Även artighetsmeddelande som "Detta är ett flerdelat meddelande i MIME-format." behövs för korrekt visning av din e-post i händelse av bilagor.
Om du fortfarande har problem gör en dbms_output.put_line(ret.code||': '||ret.text);
efter varje funktionsanrop på UTL_SMTP.
Här samma procedur men reducerad till dina behov:
