Voila je doit installer postfix en tant que relai SMTP
J'arrive a envoyer des mails depuis mon relai sur le net
mais je n'arrive pas a faire le lien avec exchange, c'est a dire que lorsque j'essai d'envoyer un mail depuis mon relai vers un user exchange il me dit utilisateur inconnu.

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


# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
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_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 = nom.domain.corp
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = exchsrv, exchsrv.domain.corp, domain.corp, domainexter.net, localhost.domainexter.net, localhost
relay_domains = domainexter.net
mynetworks = 127.0.0.0/8 192.168.1.0/24
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

Le probleme vient-il de POSTFIX ou de EXCHANGE 2007 ????

merci d'avance pour votre réponse . . .
