Hey, I have postfix set up and you will find the main configuration below. If I try to send an email from outlook it gives me: 554 Relay Access Denied. My server does have a firewall if that makes a differnce but I've allowed port 25 & 110 for mail. On Outlook I do not use secure for my smtp server. Configuration: command_directory = /usr/sbin daemon_directory = /usr/libexec/postfix alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin xxgdb $daemon_directory/$process_name $process_id & sleep 5 sendmail_path = /usr/sbin/sendmail.postfix newaliases_path = /usr/bin/newaliases.postfix mailq_path = /usr/bin/mailq.postfix setgid_group = postdrop html_directory = no manpage_directory = /usr/share/man sample_directory = /usr/share/doc/postfix-2.3.3/samples readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES smtp_sasl_auth_enable = no smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_local_domain = $mydomain unknown_local_recipient_reject_code = 450 smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination The configuration is a mess because I have editted it trying to solve this problem. Any solutions would be greatly appreciated, if you need more infomation on the porblem, please ask. Thanks, James
Hi, how did you configure the mynetworks parameter in /etc/postfix/main.cf? You should add the netmask that you use to send emails, like 192.168.1.0/24 Regards, Morenz
