Hallo zusammen Ich habe hier zu reinen Übungszwecken einen Webserver (SuSE 9.3 + XAMPP 1.53a) stehen, der per DynDNS am Internet in einer DMZ des Routers hängt. Darauf liegen einige Internetseiten. Nun habe ich eine Kontaktseite erstellt, die per PHP eine Mail an meine web.de Adresse versendet. Das PHP-Script funktioniert auch perfekt. Nun möchte ich natürlich kein offens Relay haben bzw. soll definitiv nur von diesem Rechner Mails weiterverschickt werden (uns auch nur per PHP). Kann da mal jemand bitte nachsehen, ob die Postfixconfig soweit in Ordnung ist? Danke Andy webserver:/etc/postfix # postconf -n alias_maps = hash:/etc/aliases 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_dns_lookups = yes html_directory = /usr/share/doc/packages/postfix/html inet_interfaces = 127.0.0.1 192.168.2.222 inet_protocols = all mail_owner = postfix mail_spool_directory = /var/mail mailbox_command = mailbox_size_limit = 0 mailbox_transport = mailq_path = /usr/bin/mailq manpage_directory = /usr/share/man masquerade_classes = envelope_sender, header_sender, header_recipient masquerade_domains = masquerade_exceptions = root message_size_limit = 10240000 mydestination = $myhostname, localhost.$mydomain myhostname = webserver.familieschott.prv mynetworks = 127.0.0.0/8 newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/packages/postfix/README_FILES relayhost = smtp.web.de 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_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = noanonymous smtp_use_tls = no smtpd_client_restrictions = smtpd_helo_required = no smtpd_helo_restrictions = smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination smtpd_sasl_auth_enable = no smtpd_sender_restrictions = hash:/etc/postfix/access smtpd_use_tls = no strict_rfc821_envelopes = no transport_maps = hash:/etc/postfix/transport unknown_local_recipient_reject_code = 550
