Hallo zusammen,

ich versuche schon ewig die Mailfunktion für abgeschlossene Backups, Updates etc in Gang zu bekommen aber es geht einfach nicht.

Könnt ihr mir vielleicht helfen ?

Hier mal ein Auszug aus dem mail.log:

Danke für die Hilfe.

Ich konnte das auch lösen, jedoch spinnt er jetzt an anderer Stelle.

Kann mir bitte jemand eine Hilfestellung für die Neukonfiguration geben ?

Ich hatte den DNS Eintrag auf unserem DNS-Server hinzugefügt und mit etwas Verzögerung kam auch die Testmail, aber keine Backup Notification.

Wir haben ein Cluster mit 3 Servern.

Ich bin mir auch nicht sicher, ob unser Hostname korrekt ist, da unsere Domäne von meinem Vorgänger als impeak.de angelegt wurde...

LG

ok. Also soweit passt es, bis auf Deine Domain
prx1.Impeak.local

Warum steht hier local wenn Eure Domain doch Impeak.de ist?

Aber das eigentliche Problem ist das der angegebene Absender kein Recht hat über den Relay Host zu senden.

Code: 
said: 550 "envelope sender not allowed root@prx1.Impeak.local"
 
Kann ich das ohne Sorge abändern ?
Das ist so leider auch in den Proxmox DNS Einstellungen bei searchdomain hinterlegt ...

Ich hatte immer sorge das ich etwas kaputt mache wenn ich das anpasse ...


Wie kann ich dem Absender denn das Recht dazu geben ?

Danke für deine Bemühungen :)
 
Code: 
Feb 21 10:11:46 prx1 postfix/smtp[24624]: 083CDC08A3: to=<technik@impeak.de>, relay=smtp.impeak.de[80.67.29.4]:25, delay=3, delays=2.8/0.01/0.14/0.02, dsn=5.0.0, status=bounced (host smtp.impeak.de[80.67.29.4] said: 550 "envelope sender not allowed root@prx1.Impeak.local" (in reply to MAIL FROM command))


Deine Absenderadresse root@prx1.Impeak.local wird vom Mailserver smtp.impeak.de abgelehnt.
Du musst also diem Absenderadresse mit Hilfe der canonical table von Postfix umschreiben.
Das könnte so aussehen:


Code: 
echo "root@prx1.Impeak.local prxi@impeak.de" >> /etc/postfix/canonical
echo "canonical_maps = hash:/etc/postfix/canonical" >> /etc/postfix/main.cf
postmap /etc/postfix/canonical

(prxi@impeak.de wäre dann die Absenderadresse)
Je nachdem wie der Mailserver smtp.impeak.de konfiguriert ist muss dies Adresse auch existieren oder es reicht dem Mailserver aus, wenn der Domainname impeak.de vorhanden ist.

Du kannst das einfach so ändern.
Da es sich offensichtlich um ein Unternehmen handelt frage doch bitte einmal die Admins welche für den Mailserver zuständig sind.
Eventuell musst Du Dich am SMTP Authentifizierung.
 
Ok soweit hat alles geklappt...

Außer beim PRx3

Da kommt keine Testmail, aber auch keine Fehlermeldung soweit ich sehen kann ...

main.cf ist identisch mit den anderen, mal abgesehen vom hostname ...



Aber ich danke jetzt schon, denn der dritte läuft aktuell eh nur für Testsysteme.
 
Jetzt kam was dazu ....
