Il tuo smtp ti identifica come demokrito a demokrito e demokrito non e' un
nome di host valido. Impostalo per mascherarti (gia' che siamo a
carnevale) con un tuo effettivo indirizzo. Per es.
[cowo a braveheart cowo]$ cat /etc/postfix/sender_canonical
cowo            cowo a lugbs.linux.it
root            cowo a lugbs.linux.i

Significa che postfix maschera le mail provenienti dall'utente cowo
(@braveheart.cowo.net) come cowo a lugbs.linux.it, stessa cosa per root.
