I am having a problem with Postfix on a Debian Squeeze 6.0.2 box. I think the issue has come since i did an apt-get update & upgrade recently. Anyway, the issue is that whenever i try to send email to a domain which is not listed in the $mydestinations= /etc/postfix/local_host_names directive it just gives a message bounce / bounced error and that it cannot find the recipient in the recipient list. hereunder is my recently adjusted main.cf file ( i had problems with SASLauthd and stuff due to the package upgrades but those are fixed ) : Code: alias_database = hash:/etc/aliases #mydestination = Aphrodite-Artemis, localhost.localdomain, localhost recipient_delimiter = + default_transport = error relay_transport = error sender_canonical_maps = hash:/etc/postfix/sender_canonical masquerade_exceptions = root masquerade_classes = envelope_sender, header_sender, header_recipient myhostname = mail.evil-hannie.eu program_directory = /usr/lib/postfix mydomain = evil-hannie.eu inet_interfaces = 126.96.36.199 localhost masquerade_domains = #mydestination = $myhostname, localhost.$mydomain, localhost mydestination = /etc/postfix/local-host-names defer_transports = mynetworks = 127.0.0.0/8 mynetworks_style = subnet #mailbox_command = disable_dns_lookups = no relayhost = relay_domains = $mydestination mailbox_transport = strict_8bitmime = no disable_mime_output_conversion = no smtpd_sender_restrictions = #hash:/etc/postfix/access smtpd_client_restrictions = smtpd_helo_required = no smtpd_helo_restrictions = strict_rfc821_envelopes = no #smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination smtp_sasl_auth_enable = no smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtdp_sasl_authenticated_header = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_reject_unlisted_recipient = no smtpd_sasl_local_domain = smtpd_tls_auth_only = no smtpd_use_tls = yes smtp_use_tls = yes smtp_tls_note_starttls_offer = yes smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom alias_maps = hash:/etc/aliases mailbox_size_limit = 0 message_size_limit = 10240000 content_filter = amavis:[127.0.0.1]:10024 receive_override_options = no_address_mappings home_mailbox = Maildir/ mailbox_command = Content of /etc/postfix/local-host-names is as follows : Code: localhost evil-hannie.eu mail.evil-hannie.eu Any help would be very much appreciated.
