Postfix - Temporary lookup failure

Post by hever »

Hallo zusammen,

auf einem Produktivserver erhalte ich immer mal wieder folgende Fehlermeldung:
Temporary lookup failure

Das Problem lässt sich nicht 100% reproduzieren und ist deswegen (für mich) nicht leicht zu lösen.
Es tritt bsp. auf wenn ich mehrere E-Mails nacheinander verschicke. Sei es über einen E-Mail-Client oder über eine Variation folgenden Shell Befehls:

Code: Select all

smtp-source -4c -f loadtest@mydomain.tld -S LOADTEST -t address@domain.tld -N -m 50  inet:myserver.tld
Der Client erhält dann:
smtp-source: fatal: recipient rejected: 451 4.3.0 <2address@domain.tld>: Temporary lookup failure
Das Problem ist hier wieder das dieser Fehler nicht immer auftritt. Ich habe schon manche Nächte damit verbracht das Problem zu lösen und konnte dann gut 1000 Mails ohne Probleme verschicken und auch in den Tagen darauf (tagsüber) gab es keine Probleme. Immer wenn ich glaube es gelöst zu haben kommt es nach ein paar Tagen wieder. Die Adresse 2address@domain.tld existiert bzw. ein entsprechender catchall. Mal funktioniert eine E-Mail-Adresse, mal nicht (es liegt also nicht daran, das die Adresse nicht existiert).

Nachtrag:
Momentan ist der Server kaum nutzbar und ich erhalte ebenfalls die Fehlermeldung
smtp-source: fatal: data 451 4.3.0 Error: queue file write error
Nach einem Postfix restart gehen ca. 100 Mails raus, dann kommen die Fehler wieder.

Lösungsansätze:
- Das Problem trat zunächst auf als ich noch keinen lokalen DNS-Server installiert hatte. Nach der Installation von bind9 schien das Problem das erste mal verschwunden.
- Als das Problem dann wieder auftrat habe ich proxymap (http://www.postfix.org/proxymap.8.html) eingesetzt und die Wake up time (http://www.postfix.org/master.5.html) für den smtp Dienst auf 60 gesetzt. (Proxymap alleine hat nicht viel gebracht aber in Verbindung mit der Wake up time schon.)

Mögliche Ursachen (meiner Ansicht nach):
- Ich vermute stark das es irgendetwas mit der DNS-Namensauflösung zutun hat, ich kann jedoch nicht herausfinden was. Ich habe in einer Mailingliste gelesen, das Fehler wie mail_addr_find: address@domain.tld -> (try again) wohl teilweise auf eine DNS-Namensauflösung zurückzuführen sind, der source code an der Stelle hat mich aber auch nicht besonders weiter gebracht. (http://groups.google.com/group/list.pos ... 2cb7924052)
- Ich denke nicht das es am MySQL Server liegt, folgender Befehl (fragt 1000 mal hintereinander die DB ab) läuft problemlos durch.

Code: Select all

 yes address@domain.tld | sed 1000q | postmap -q - mysql:/etc/postfix/mysql_virtual_alias_maps.cf
Ich möchte nicht einfach wild etwas verändern sondern das Problem verstehen, darum stelle ich jetzt ein paar Fragen:
Woran kann dieses Problem liegen, was könnte alles damit zutun haben ?
Sollte ich die Wake up time nochmal verändern?
Sollte ich versuchen den lokalen cache im DNS Server zu verändern?
Kann ich irgendwie einstellen, das wenn der Temporary Lookup Failure kommt, Postfix einfach nochmal versucht die Mail zuzustellen?
Kann es sein das Postfix nach einigen Tagen einfach überläuft? Scheint mir nicht so aber vielleicht doch ?

Momentan ist der Server kaum nutzbar und ich erhalte ebenfalls die Fehlermeldung

Nach einem Postfix restart gehen ca. 100 Mails raus, dann kommen die Fehler wieder.
Diesen Fehler hab ich selbst durch das debuggen mit smtp -v verursacht.
Trotzdem geht momentan keine Mail raus. Immer kommt ein Temporary Lookup Failure.
Das ist gut und schlecht.

Es gehen nach einem Postfix restart also ca. 50 Mails raus und dann kommt der Lookup Failure.

Es gibt Probleme mit Deiner MySQL-Verbindung:

Ich habe cleanup mail in den verbose modus gesetzt, aber erhalte keine weiteren Informationen. Wie kann ich den Fehler verfolgen, also sehen, was das lookup problem genau ist ?

Re: Postfix - Temporary lookup failure

Post by hever »

/etc/postfix/mysql_virtual_alias_maps.conf:
hosts = 127.0.0.1
user = postfix
password = ***

dbname = ***

query = SELECT target_address
FROM `view_emailaccount_alias`
WHERE alias REGEXP '(^%s.?$)'
AND (
NOW() BETWEEN `forward_start` AND `forward_end`
OR forward_start IS NULL AND forward_end IS NULL )
ORDER BY forward_start DESC
LIMIT 1
Die DB Struktur ist zu komplex um sie jetzt hier zu posten.

Ich habe dort nicht weiter nach dem Fehler gesucht weil postmap immer die richtige Mailadresse zurückgeliefert hat. Meinst du ich sollte dort nochmal nach dem Fehler suchen? Es gibt ein paar spam adressen mit einigen ungültigen Zeichen die zu einem Temporary lookup failure führen, weil die REGEXP fehlschlägt, aber alle anderen Adressen sind simple und funktionieren meist. (Meist weil sonst der TLO fehler kommt... In den DB logs ist aber nichts ungewöhnlich und ich kann die queries selber erfolgreich ausführen.)
Nochmal die Frage: Wenn postmap funktioniert sollte es doch nicht an der DB liegen oder?

Re: Postfix - Temporary lookup failure

Post by hever »

Ich habs nochmal überprüft bei einem " Error: queue file write error" der doch manchmal noch kommt und bei einem " Temporary lookup failure" erscheinen entsprechende abfragen im mysql.log. Postfix kann sich also mit dem MySQL Server verbinden und auch eine Abfrage durchführen. Es wird wohl so sein das manchmal einfach kein Ergebnis zurückgeliefert wird. (Bei einer Adresse die zuvor noch funktionierte). Also liegt es wohl schon irgendwie an der DB.

Immer noch: Nur postmap funktioniert einwandfrei ?

Welche MySQL Server Einstellungen beeinflussen dieses Verhalten?

Re: Postfix - Temporary lookup failure

Versuche es mal mit:

Code: Select all

user = dbuser
password = dbpass
hosts = localhost
dbname = dbname
query = SELECT target_address FROM view_emailaccount_alias WHERE alias='%s' AND ( NOW() BETWEEN forward_start AND forward_end OR forward_start IS NULL AND forward_end IS NULL ) ORDER BY forward_start DESC LIMIT 1
Ein Beispiel-Row mit reellen Daten (eMail-Adresse darfst Du ersetzen) und das Tabellen-Schema wären dennoch hilfreicher...

Re: Postfix - Temporary lookup failure

(Ich habe gerade proxymap also "proxy:" vor jeder lookup table rausgenommen und mom. erhalte ich dadurch Fehlermeldungen mit denen ich etwas anfangen kann.)
"warning: connect to mysql server localhost: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)"
Ich versuche jetzt erstmal die Fehler zu beheben und werde weiteres Berichten.

Re: Postfix - Temporary lookup failure

Post by hever »

So JoeUser,

nachdem ich proxy: entfernt hatte bekam ich endlich einige Fehlermeldungen mit denen ich etwas anfangen konnte.

Letztendlich habe ich in meinen Queries das REGEXP durch ein LIKE ersetzt und seitdem gab es bisher keine Probleme mehr.
(Ich hab mal ein paar tausend mails durchgeschickt.)
Ich denke das @ hat in der REGEXP manchmal für irgendwelche Probleme gesorgt, auch wenn ich mir nicht erklären kann warum nur manchmal oder überhaupt.

Ich hoffe sehr das dieses Thema endgültig erledigt ist. Ich werde jetzt noch ein paar kleine Fehler überprüfen und dann auch proxy wieder verwenden. (Es ist schon wieder so spät und diesen Erfolg hatte ich nun schon öfters, hoffentlich hat es wirklich nicht mysteriöser weise etwas mit der Zeit zutun)

Ansonten vielen Dank Joe User!
Du hast mir wirklich mit Weitblick geholfen und ich hätte wahrscheinlich die query nicht nochmal überdacht.
