Hi folks. I’m on a LAN, with a mail server on OS X Server Mountain Lion. It’s running Postfix as a mail server.
My LAN has a 192.168.x.x range. I’m getting that error when an app I’m developing, is trying to send an email out through this email server to the internet. A gmail address specifically. My main.cf: biff = no command_directory = /usr/sbin config_directory = /Library/Server/Mail/Config/postfix daemon_directory = /usr/libexec/postfix data_directory = /Library/Server/Mail/Data/mta 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 dovecot_destination_recipient_limit = 1 html_directory = /usr/share/doc/postfix/html imap_submit_cred_file = /Library/Server/Mail/Config/postfix/submit.cred inet_interfaces = loopback-only inet_protocols = all mail_owner = _postfix mailbox_size_limit = 0 mailq_path = /usr/bin/mailq manpage_directory = /usr/share/man message_size_limit = 10485760 mydomain_fallback = localhost mynetworks = 192.168.0.0/24 127.0.0.0/8 # RF newaliases_path = /usr/bin/newaliases queue_directory = /Library/Server/Mail/Data/spool readme_directory = /usr/share/doc/postfix recipient_delimiter = + sample_directory = /usr/share/doc/postfix/examples sendmail_path = /usr/sbin/sendmail setgid_group = _postdrop smtpd_client_restrictions = permit_mynetworks permit_sasl_authenticated permit smtpd_recipient_restrictions = permit_sasl_authenticated permit_mynetworks reject unauthdestination permit smtpd_tls_ciphers = medium smtpd_tls_exclude_ciphers = SSLv2, aNULL, ADH, eNULL tls_random_source = dev:/dev/urandom unknown_local_recipient_reject_code = 550 use_sacl_cache = yes postconf: warning: /etc/postfix/main.cf: unused parameter: smtpd_relay_restrictions=permit_mynetworks permit_sasl_authenticated reject_unauth_destination I’m hosting a handful of local and FQDN on the LAN, and I develop using a machine.local naming scheme. Just wondering how I can whitelist my internal domains to get outgoing emails past my mail server. Not really sure what to post here as well. Any insight appreciated.
