LinuxQuestions.org - Can't send mail from client with postfix

Hi!

I have a problem, i try to send a mail with Outlook but i get an error meassage "Realy access denied" so the mail is not been sent.

How i do?

Here is my main.cf file:

//START

# 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 (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.

alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = $mydomain
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mynetworks = 10.0.0.0/24
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
virtual_alias_maps = hash:/etc/postfix/virtual
smtpd_recipient_restrictions = permit_mynetworks reject_unauth_destination permit_inet_interfaces permit_sasl_authenticated
message_size_limit = 20480000
smtpd_sasl_auth_enable = yes
smtpd_delay_reject = no
masquerade_domains = $mydomain
myhostname = hd.hvalstaddata.com

//END
