please take a look a this asap
i locked mail for my office...


I just completed installation of
Postfix and Courier using MySQL, following isp style config with
virtual user

I'm happy every thing seems ok,
i configured it as mx for my domain
i can receive mails from outside and from local users

every pop3 client can't send mail outside every time is relay not
allowed

the postfix server has 2 ip address
1) lan 192.168.1.11
1) wan public & static xx.yy.xxx.yyy

this is my postfix configuration

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
broken_sasl_auth_clients = yes
config_directory = /etc/postfix
inet_interfaces = all
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
myhostname = mail.bridgecomm.it
mynetworks = 127.0.0.0/8
myorigin = /etc/mailname
proxy_read_maps = $local_recipient_maps $mydestination
$virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps
$virtual_mailbox_domains $relay_recipient_maps $relay_domains
$canonical_maps $sender_canonical_maps $recipient_canonical_maps
$relocated_maps $transport_maps $mynetworks
$virtual_mailbox_limit_maps
recipient_delimiter = +
relayhost =
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
smtpd_recipient_restrictions = permit_mynetworks,
permit_sasl_authenticated, reject_unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_tls_cert_file = /etc/postfix/smtpd.cert
smtpd_tls_key_file = /etc/postfix/smtpd.key
smtpd_tls_session_cache_database = btree:${queue_directory}/

smtpd_use_tls = yes
transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf
virtual_alias_domains =
virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-
virtual_forwardings.cf, mysql:/etc/postfix/mysql-
virtual_email2email.cf
virtual_gid_maps = static:5000
virtual_mailbox_base = /home/vmail
virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-

*****
imho default configuration of mta should deliver mail outside for it's
users...
it should be not 'relay'

really thanks for any help.
