Hola tengo un gran problema en el nuevo servidor de correo que he puesto. resulta que a ciertos usuarios no les deja enviar correos. Por lo que veo en los logs dice: 450 Client host rejected: cannot find your hostname, [XX.XX.XX.XX] La salida del postconf de postfix es la siguiente de abajo Puede ser que esta linea: smtpd_helo_restrictions = permit_mynetworks, reject_invalid_hostname lo este probocando? Que opinais? me podeis ayudar? muchas gracias server:~ # postcoonf -n -bash: postcoonf: command not found server:~ # postconf -n alias_maps = hash:/etc/aliases, ldap:/etc/postfix/ldapalias_maps_member.cf, ldap:/etc/postfix/ldapalias_maps.cf biff = no canonical_maps = hash:/etc/postfix/canonical command_directory = /usr/sbin config_directory = /etc/postfix content_filter = daemon_directory = /usr/lib/postfix debug_peer_level = 2 defer_transports = disable_mime_output_conversion = no home_mailbox = html_directory = /usr/share/doc/packages/postfix/html inet_interfaces = all inet_protocols = all local_recipient_maps = $alias_maps, ldap:/etc/postfix/ldaplocal_recipient_maps.cf mail_owner = postfix mail_spool_directory = mailbox_command = mailbox_size_limit = 20480000 mailbox_transport = lmtp:unix:/var/lib/imap/socket/lmtp mailq_path = /usr/bin/mailq manpage_directory = /usr/share/man masquerade_classes = envelope_sender, header_sender, header_recipient masquerade_domains = ldap:/etc/postfix/ldapmasquerade_domains.cf masquerade_exceptions = root message_size_limit = 10240000 mydestination = $myhostname, localhost.$mydomain, $mydomain, ldap:/etc/postfix/ldapmydestination.cf mydomain = xxx.com myhostname = server.xxx.com mynetworks = 127.0.0.0/8 mynetworks_style = subnet newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/packages/postfix/README_FILES relayhost = relocated_maps = hash:/etc/postfix/relocated sample_directory = /usr/share/doc/packages/postfix/samples sender_canonical_maps = hash:/etc/postfix/sender_canonical sendmail_path = /usr/sbin/sendmail setgid_group = maildrop smtp_enforce_tls = no smtp_sasl_auth_enable = no smtp_sasl_security_options = noanonymous smtp_tls_enforce_peername = yes smtp_tls_per_site = ldap:/etc/postfix/ldapsmtp_tls_per_site.cf smtp_use_tls = yes smtpd_banner = smtpd_client_restrictions = permit_mynetworks, ldap:/etc/postfix/ldapaccess.cf, reject_unknown_client smtpd_helo_required = yes smtpd_helo_restrictions = permit_mynetworks, reject_invalid_hostname smtpd_recipient_restrictions = permit_sasl_authenticated, permit_auth_destination, permit_mynetworks, reject_unauth_destination, reject smtpd_sasl_auth_enable = yes smtpd_sender_restrictions = ldap:/etc/postfix/ldapaccess.cf, reject_unknown_sender_domain smtpd_tls_CApath = /etc/ssl/certs smtpd_tls_auth_only = no smtpd_tls_cert_file = /etc/ssl/servercerts/servercert.pem smtpd_tls_key_file = /etc/ssl/servercerts/serverkey.pem smtpd_use_tls = yes strict_8bitmime = no strict_rfc821_envelopes = yes transport_maps = ldap:/etc/postfix/ldaptransport_maps.cf unknown_local_recipient_reject_code = 550 virtual_alias_domains = ldap:/etc/postfix/ldapvirtual_alias_maps.cf virtual_alias_maps = ldap:/etc/postfix/ldaplocal_recipient_maps.cf ###ERROR El mensaje no se pudo enviar, uno de los destinatarios fue rechazado por el servidor.
