[solved] Postfix sendet keine Mails....

King_S · 29 Apr. 2005

Hallo,
habe nach der Anleitung von www.linux-tin.org mir postfix, cyrus und fetchmail eingerichtet. Alle Dienste funktionieren, selbst cyrus. Nur kann ich keine Mails mit Postfix senden, weder über telnet noch über KMail.

Wenn ich eine E-Mail senden will, kommt folgendes:

Code:

450 Client host rejected: cannot find your hostname, [::1]

KMail gibt nen ähnlich Fehler aus. Außerdem reagiert der lokale Mail Server nicht auf mail.linux.lc, so wie es auch in der main.cf geschrieben steht. Könnte es ein DNS Problem sein? Wenn ja, wie behebe ich es?

Hier postconf -n:

Code:

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
broken_sasl_auth_clients = yes
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/lib/postfix
debug_peer_level = 2
default_destination_concurrency_limit = 10
fallback_transport = cyrus
local_destination_concurrency_limit = 2
mail_owner = postfix
mailbox_command = /usr/lib/cyrus/bin/deliver
mailbox_transport = lmtp:unix:/file/name
mailq_path = /usr/bin/mailq
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, $mydomain
mydomain = linux.lc
myhostname = mail.linux.lc
mynetworks_style = subnet
myorigin = $mydomain
newaliases_path = /usr/bin/newaliases
queue_directory = /var/spool/postfix
relayhost = smtp.mail.yahoo.de
sample_directory = /usr/share/doc/packages/postfix/samples
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
smtpd_banner = $myhostname ESMTP
smtpd_client_restrictions = reject_unknown_client, permit_mynetworks
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_relay_domains
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous
unknown_local_recipient_reject_code = 450

Hoffe, das mir jemand helfen kann, der rest scheint dann soweit zu funktionieren

poste mal die /etc/hosts

dort fehlen sehr wahrscheinlich die Einträge und ipv6 solltest du auch mal deaktivieren ...

King_S · 29 Apr. 2005

Also die /etc/hosts:

# special IPv6 addresses
::1 localhost ipv6-localhost ipv6-loopback

fe00::0 ipv6-localnet

ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
127.0.0.1 famkrinetzki.dyndns.org
127.0.0.2 linux.lc linux

und mit
install ipv6 /bin/true

in der Datei /etc/modprobe.conf ipv6 deaktiviert, oder?

oc2pus · 29 Apr. 2005

127.0.0.1 localhost

so einer fehlt dir in deiner /etc/hosts

King_S · 29 Apr. 2005

So meine /etc/hosts sieht nun so aus:

Code:

# special IPv6 addresses
::1 localhost ipv6-localhost ipv6-loopback

fe00::0 ipv6-localnet

ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
127.0.0.1 localhost famkrinetzki.dyndns.org
127.0.0.2 linux.lc linux

Trotzdem funktioniert der Mail versand nicht, immer noch der Fehler wie ganz oben beschrieben, und auf mail.linux.lc reagiert postfix auch nicht, KMail gibt dann aus, der Rechner wurde nicht gefunden. Sobald ich dann aber localhost angebe, komme ich wieder zu der 450 Fehlermeldung

Code:

450 Client host rejected: cannot find your hostname, [127.0.0.1]

192.168.11.42 paul.zuhause.nil paul
192.168.11.2 franz.zuhause.nil franz

so, den 127.0.0.1 ganz oben und teste mit ping localhost ==> 127.0.0.1, dann geht es

King_S · 29 Apr. 2005

Hmm...hat auch nichts geändert

hier mal die Konsole:

oh Helden des Alltags unterwegs ....

127.0.0.2 linux.lc linux != 127.0.0.1 localhost

und wenn du zu 127.0.0.1 connectest kennt deine Namensauflösung nur localhost und nicht linux.lc !!

wenn du den test mit ich@localhost als Absender durchführst geht es ...

King_S · 29 Apr. 2005

Irgendwie nicht....

Code:

kings@linux:~> telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.

220 mail.linux.lc ESMTP

oc2pus · 29 Apr. 2005

hast du nach der Änderung an der /etc/hosts den postfix neu gestartet ?

Ansonsten poste mal deine gesamte main.cf OHNE Kommentare

und die aktuelle /etc/hosts

King_S · 29 Apr. 2005

Selbst nach

Code:

rcpostfix restart

Hat sich nichts geändert....

Sollte ich vielleiht mal linux.lc gegen localhost tauschen?

oc2pus · 30 Apr. 2005

ähm, für wen ist dein Postfix zuständig ?

mynetworks= .... ???

dort mal deine netzmaske und localhost (127.0.0.1/8) aktivieren. rcpostfix restart und neuer Test...

dabei mit tail -f /var/log/mail beobachten was passiert.

King_S · 30 Apr. 2005

Also........da ich dank KDE 3.4 mein SuSE 9.1 reinstallen musste, begann ich von vorne, und siehe da, es funktioniert ^^

Code:

linux:/home/kings # telnet localhost 25

Also ich wollte nur schicken und testen....malsehen ^^
.
250 Ok: queued as A426641933

221 Bye

linux:/home/kings # sendmail -q

Nur woran es lag, keine Ahnung...habe das mit mynetworks auch angepasst, kann sein dass das den fehler behoben hat....auf alle Fälle läuft es jetzt ^^.....

@oc2pus:
Oder wollste nochmal die main.cf sehen? Falls jemand ein ähnliches Problem hat.....
