Ok, by replacing virtual_maps = proxy:mysql:/etc/postfix/mydomain.cf to
virtual_mailbox_domains = mysql:/etc/postfix/mydomain.cf, it works !!!

But now, the problem is to set the good uid and gid which were defined
like this in postfix

virtual_gid_maps = proxy:mysql:/etc/postfix/mygid.cf
virtual_uid_maps = static:33

With this configuration:

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=mail:mail argv=/usr/lib/dovecot/deliver -d $(recipient)

   socket listen {
     master {
       path = /var/run/dovecot/auth-master
       mode = 0660
       user = mail
       group = mail
   }

I get the following error message

Fatal: setgid(33(www-data)) failed with euid=8(mail), gid=8(mail),
egid=8(mail): Operation not permitted

Any ideas ?

Thanks
