[postfix-users] DANE spezifische Konfigurationsparameter (>=2.11)
by Christian Bricart 26 Aug '14

26 Aug '14

hallo zusammen, in jeglichen Howtos/Folien/etc zu Konfiguration von DANE finde ich immer wieder folgendes: $ postconf -e "smtpd_use_tls = yes" $ postconf -e "smtp_dns_support_level = dnssec" $ postconf -e "smtp_tls_security_level = dane" erstens: wieso eigentlich "smtpD_use_tls"..? will ich nicht in den nächsten zwei Zeilen diesen Postfix als CLient konfigurieren? und zweitens: wenn DANE sowieso erst ab 2.11 möglich ist, warum wird hier eine als seit 2.3 abgekündigte Option wieder eingeführt..? Sollte dort nicht dann immer direkt mit smtp[d]_tls_security_level dokumentiert werden? my 2 cents Christian

[postfix-users] Frage zu smtpd_sender_login_maps
by Matthias Schmidt 25 Aug '14

25 Aug '14

Hallo, wie handhabe ich da meine Mailingliste? Die ganzen mailman email Konten haben ja keinen Login bei mir. Oder muss ich dann reject_unauthenticated_sender_login_mismatch nur bei submission und ssl in der master.cf setzen? Der mailman schickt ja seinen Kram auf port 25. Dank und Gruss Matthias

[postfix-users] Spam-Relay via gekapertem Useraccount
by Matthias Schmidt 24 Aug '14

24 Aug '14

Hallo, ich seh in meinem log viele viele mails, die von irgendwoher kommen und meist an französische yohoo Adressen gehen. ich hab den Server via http://mxtoolbox.com/ getestet und das Tool sagt kein Open Relay. Nachdem ich dem noch weiter in den Logs gewühlt habe, sieht es so aus als ob ein User-Account geknackt wurde. Das entsprechende Passwort hab ich gleich mal geändert. amavis wirft entsprechend folgende Warnung aus: Open relay? Nonlocal recips but not originating Kann ich das irgendwie unterbinden, so dass das senden nur von lokalen Account aus erlaubt ist, trotz geknacktem login? Im log sieht das so aus: Aug 21 14:22:52 mcgregor postfix/smtpd[61457]: connect from 248-60-132-95.pool.ukrtel.net[95.132.60.248] Aug 21 14:22:55 mcgregor postfix/smtpd[61457]: BD714344E77: client=248-60-132-95.pool.ukrtel.net[95.132.60.248], sasl_method=LOGIN, sasl_username=xxxxxxx Aug 21 14:23:00 mcgregor postfix/cleanup[60895]: BD714344E77: message-id=<B3A6F10C541CA98284500355DD992F56(a)schmidt-system.de> Aug 21 14:23:00 mcgregor postfix/qmgr[52031]: BD714344E77: from=<xavierjoly20(a)yahoo.com>, size=1663, nrcpt=8 (queue active) Aug 21 14:23:00 mcgregor amavis[54462]: (54462-03) process_request: fileno sock=15, STDIN=0, STDOUT=1 Aug 21 14:23:00 mcgregor amavis[54462]: (54462-04) ESMTP::10024 /var/amavis/tmp/amavis-20140821T141253-54462: <xavierjoly20(a)yahoo.com> -> <isabelle.andpae(a)gmail.com>,<fruleux.svt(a)laposte.net>,<juliette.jamey(a)laposte.net>,<legendre.jeanphilippe(a)neuf.fr>,<bailleulcastelain(a)nordnet.fr>,<gerardcourbet(a)sfr.fr>,<s.rey(a)we-ef.com>,<juliesaerens(a)yahoo.fr> SIZE=1663 Received: from mcgregor.admilon.net ([127.0.0.1]) by localhost (mcgregor.admilon.net [127.0.0.1]) (amavisd-new, port 10024) with ESMTP; Thu, 21 Aug 2014 14:23:00 +0900 (JST) Aug 21 14:23:00 mcgregor amavis[54462]: (54462-04) smtp connection cache, dt: 214.3, state: 1 Aug 21 14:23:00 mcgregor amavis[54462]: (54462-04) smtp connection cache, dt: 214.3 -> disabling Aug 21 14:23:00 mcgregor amavis[54462]: (54462-04) body hash: ebb4b50a64e9df85ce48d1c539e100c0 Aug 21 14:23:00 mcgregor amavis[54462]: (54462-04) Checking: enF3iG7mT0bU [95.132.60.248] <xavierjoly20(a)yahoo.com> -> <isabelle.andpae(a)gmail.com>,<fruleux.svt(a)laposte.net>,<juliette.jamey(a)laposte.net>,<legendre.jeanphilippe(a)neuf.fr>,<bailleulcastelain(a)nordnet.fr>,<gerardcourbet(a)sfr.fr>,<s.rey(a)we-ef.com>,<juliesaerens(a)yahoo.fr> Aug 21 14:23:00 mcgregor amavis[54462]: (54462-04) 2822.From: <xavierjoly20(a)yahoo.com> Aug 21 14:23:00 mcgregor amavis[54462]: (54462-04) Open relay?

[postfix-users] Mails an root
by Daniel Thielking 16 Aug '14

16 Aug '14

Hallo Postfix-User, Ich habe bei mir Postfix eingerichtet so, dass ich über smtp.1und1.de meine Mails versende. Wenn ich mail -s "Test" daniel.thielking(a)ias.rwth-aachen.de verwende, wird diese Mail auch in mein Postfach gesendet. Sobald ich versuche: mail -s "Test" root oder mail -s "Test" root@localhost, werden diese weder dem root-User noch dem eigentlich eingerichteten Alias weitergeleitet. (Der alias geht an daniel.thielking(a)ias.rwth-aachen.de) Es werden auch keine Systemmails an root oder den alias weiter geleitet. Hier meine main.cf: # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default # is /etc/mailname. #myorigin = /etc/mailname smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h readme_directory = no # TLS parameters smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination myhostname = server.thielking-vonessen.de alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = server.thielking-vonessen.de, localhost.thielking-vonessen.de, localhost mynetworks = 127.0.0.0/8 mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all relayhost = smtp.1und1.de:587 default_transport = smtp relay_transport = smtp inet_protocols = ipv4 #1und1.de einstellung für den SMTP Versand smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = noanonymous smtpd_use_tls=yes smtp_enforce_tls = no smtp_tls_security_level = may Woran kann das liegen? -- _____________________________________________________ Auszubildender Fachinformatiker für Systemintegration RWTH Aachen Lehrstuhl für Integrierte Analogschaltungen Raum 24C 313 Walter-Schottky-Haus Sommerfeldstr. 24 D-52074 Aachen www.ias.rwth-aachen.de Email: Daniel.Thielking(a)ias.rwth-aachen.de Phone: +49-(0)241-80-27771 FAX: +49-(0)241-80-627771 _____________________________________________________

[postfix-users] smtpd_proxy_filter und Amavis -> postfix/submission/smtpd[24419]: fatal: smtp:[127.0.0.1]:10026: valid hostname or network address required
by Jakob-Matthias Böttger 06 Aug '14

06 Aug '14

Hallo zusammen, Ich hänge irgendwo in einem Denkfehler. Amavis ist zwecks DKIM signierung auf 10024 und 10026 eingerichtet. Mittels content_filter funktioniert es auch soweit. Stelle ich aber nun z.B. submission auf smtpd_proxy_filter=smtp:[127.0.0.1]:10026 bekomme ich postfix/submission/smtpd[24419]: fatal: smtp:[127.0.0.1]:10026: valid hostname or network address required postfix/master[19921]: warning: process /usr/lib/postfix/smtpd pid 24419 exit status 1 postfix/master[19921]: warning: /usr/lib/postfix/smtpd: bad command startup -- throttling im Anhang die postconf -nf und postconf Mf Resultate mit der unter content_filter funktionierender Ćonfig Beste Grüße Jakob

[postfix-users] Wie Anzahl der Mails/Zeiteinheit für bestimmte Clients beschränken?
by Peter Heitzer 04 Aug '14

04 Aug '14

Gelegentlich kommt es bei uns vor, daß ein Client aufgrund einer Infektion mit Schadsoftware zur Spamschleuder wird und einige tausende von Mails verschickt, bis es von uns entdeckt und unterbunden wird. Deshalb hätte ich gerne eine Möglichkeit, die Mailrate für Clients auf einen "normalen" Wert, z.B. max. 10/Minute zu beschränken. Diese Beschränkung soll für alle Clients in $mynetworks gelten, mit Ausnahme einiger Server. Was käme dafür am ehesten in Frage?
