Debian ETCH, postfix alias and forward doesn't work

[flurpiti]

Hi there!

I had to replace my former postfix mail server under linux mandrake 8 ( hacked)
to an up to date postfix under debian ETCH.
parameters doesn't seems to exactly the same as before.
After a few solved problem, I have been able to run the mail server,
that is getting the emails and sending them.
The trouble is that alias doesn't work nor forwarding using .forward files in users homes.
I have an aliases file, and an aliases.db file made using postalias aliases

my main.cf file is this:

-----------------------------------------
# See /usr/share/postfix/main.cf.dist for a commented, more complete version

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
delay_warning_time = 4h

# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

myhostname = mail.esgt.cnam.fr

allow_mail_to_commands=alias,forward

alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases

mydomain=esgt.cnam.fr
myorigin=esgt.cnam.fr

mydestination = $myhostname, $mydomain,localhost.$mydomain,localhost

mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

------------------------------------
my alias file like this:

--------------------------------
pierre.clergeot: pclergeot
michel.kasser: kasser
jean-marc.baca: jmbaca
andre.balandier: balandier
isabelle.benibri: benibri

------------------------------


Any Idea of what's happening? solution?

Did you run

newaliases

and restart Postfix after you've modified /etc/aliases?
Any errors in the mail log?
