i am trying to send an email with my freebsd server using postfix and dbmail to an external adress. I have noticed the following things: MYSERVER -> MYSERVER = OKAY EXTERNALSERVER -> MYSERVER = OKAY MYSERVER -> EXTERNALSERVER = ERROR(454 4.7.1 Relay access denied) Why do i get this error? i think it has something to do with my main.cf MAIN.CF queue_directory = /var/spool/postfix command_directory = /usr/local/sbin daemon_directory = /usr/local/libexec/postfix data_directory = /var/db/postfix mail_owner = postfix default_privs = nobody myhostname = server.domain.nl mydomain = domain.nl myorigin = $mydomain inet_interfaces = all virtual_transport = dbmail-lmtp:localhost:24 virtual_mailbox_domains = domain.nl unknown_local_recipient_reject_code = 550 mynetworks = 127.0.0.0/8 [::1]/128 smtpd_helo_required = yes strict_rfc821_envelopes = yes debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 sendmail_path = /usr/local/sbin/sendmail mailq_path = /usr/local/bin/mailq setgid_group = maildrop html_directory = /usr/local/share/doc/postfix manpage_directory = /usr/local/man sample_directory = /usr/local/etc/postfix readme_directory = /usr/local/share/doc/postfix inet_protocols = ipv4 smtpd_recipient_restrictions = permit_sasl_authenticated permit_mynetworks reject_unauth_destination Thanks in advance
