Hi all, I've got a problem here. I am trying to setup email on a new server using Postfix. Can send emails to local users but anything else fails with the error "Relay access denied". Attached more detailed info below - can provide more if this would help. Any help would be great Thanks. From logs: postfix/smtpd[22171]: warning: ::1: address not listed for hostname localhost postfix/smtpd[22141]: connect from unknown[::1] postfix/smtpd[22141]: NOQUEUE: reject: RCPT from unknown[::1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<www.mydomain.com> postfix/smtpd[22141]: lost connection after RCPT from unknown[::1] postfix/smtpd[22141]: disconnect from unknown[::1] Contents of /etc/postfix/main.cf: Code: smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no append_dot_mydomain = no readme_directory = no # TLS parameters smtpd_tls_cert_file = /etc/ssl/certs/smtpd.crt smtpd_tls_key_file = /etc/ssl/private/smtpd.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_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 mydestination = mail.mydomain.com, mydomain.com, localhost.localdomain, localhost relayhost = mynetworks = 127.0.0.0/8, 192.168.0.0/16 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all myorigin = /etc/mailname inet_protocols = all home_mailbox = Maildir/ mailbox_command = smtpd_sasl_local_domain = smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtp_tls_security_level = may smtpd_tls_security_level = may smtpd_tls_auth_only = no smtp_tls_note_starttls_offer = yes smtpd_tls_CAfile = /etc/ssl/certs/cacert.pem smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom myhostname = mail.mydomain.com
Fixed by replacing "mynetworks = 127.0.0.0/8, 192.168.0.0/16" with "mynetworks_style = subnet" Thanks.
