I still got one instance of undelivered mail problem after changing my
virtual alias maps. The same problem, it declared the user still as
unknown, though already add a localhost at the last part of the user.

I did not forgot to restart postfix and already re-run postmap on virtual file

#/etc/postfix/virtual
giovanni.claveriamydomain.com giovanni.claverialocalhost
giovanni.claveriamail.mydomain.com giovanni.claverialocalhost

and my mydestination entry at main.cf is
mydestination = $myhostname, localhost.$mydomain, localhost

and is there a significant on my /etc/hosts file, here' s the entries.

127.0.0.1 localhost.localdomain localhost
192.168.100.254 mail.mydomain.com mail #this is my eth0

or should I append mail.mydomain.com beside localhost?

TIA
