So I make some test before go to sleep, and it's not work fully as I want :
  - When I try to send a mail for a other domain, I'm reject, it's OK.
  - I try with an other account, and, all incoming mails go in the first 
mailbox 
(us...@domain1.tld), but I can send mails from each of 2 available domains (the 
2 others are in production, so I just declare them, but not change DNS entries 
at this moment).
  - When I try with "virtual_alias_domains" (and emptied "mydestination"), it's 
reject all incoming mails.

The line with error when incoming mails are reject :
Dec 21 01:16:36 mailserver postfix/error[5138]: A5BF24081E: 
to=<us...@domain1.tld>, orig_to=<test...@domain1.tld>, relay=none, delay=0.47, 
delays=0.18/0.1/0/0.19, dsn=5.0.0, status=bounced (User unknown in virtual 
alias 
table)
Dec 21 01:16:36 mailserver postfix/error[5139]: 96B8540815:

delays=0.25/0.17/0/0.27, dsn=5.0.0, status=bounced (User unknown in virtual 
alias table)


All accounts are Unix account.
user1 and user2 exists in /home directory and the directory "Maildir" exists 
too 
for both.


Configuration :

----

/etc/postfix/virtual :

----

/etc/aliases is empty
/etc/mailname contains only one line  :

Thanks.
