Formmail con allegato

[Gnappoide]

Ciao a tutti,
avrei bisogno di un consiglio su uno script in php che mandi una mail (ad un destinatario predefinito) con la possibilità di allegare un file da un sito.
Lo so che ce ne sono molti in giro, io ne usavo uno che faceva un controllo sui campi, sulla validità dell'indirizzo mail, sul limite della grandezza del file e sulla sua estensione.
Andavo tanto bene, solo che mi funzionava a meraviglia con altervista.
Dopo che ho cambiato hosting, adesso mi arrivano le mail con l'allegato che pesa 0kb.. :help:

[Pappe]

potresti allegare quello che usavi per modificarlo..

Hai ragione scusa ;)
