So, ich habe lange selbst versucht den Fehler zu finden, habe rumprobiert und rumgetestet aber ich habe nicht annähernd ne Ahnung woran das aktuelle Problem liegt. Ich habe in den letzten Tagen nichts am Mailserver geändert, ausser dass ich in der /etc/postfix/main.cf den content_filter kurzzeitig rausgenommen habe. Also mein aktuelles Problem ist folgendes:

Seit ein paar Tagen kann man keine Mails mehr über meinen Mailserver verschicken. Man wird nach dem Passwort gefragt, wenn man es eingibt wird man weietr gefragt, da das Passwort anscheint nicht funktioniert. Also habe ich ins Maillog geschaut und habe folgendes gefunden:

Code: 
Oct 10 18:54:10 quark postfix/smtpd[26156]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory

Oct 10 18:54:14 quark postfix/smtpd[26156]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory

Ganz grob, sind das folgende Fehlermeldungen:

Code: 
SASL authentication failure: cannot connect to saslauthd server: No such file or directory
SASL authentication failure: Password verification failed
SASL PLAIN authentication failed: generic failure

So, ab dem Zeitpunkt habe ich nun garkeine Ahnung mehr woran es liegen könnte. Saslauthd läuft. Ich habe nun auch keine wirkliche Ahnung was für Informationen ihr nun braucht um mir dabei zu helfen den Fehler zu finden, darum paste ich mal ein paar Sachen, die meist relativ wichtig sind:

SMTP AUTH can't work!

Hmm, jetzt wo ich saslfinger nutze scheint sich da ein Fehler rauszukristalliesieren. Zum einen weil ich "zimbra" nicht nutze und zum anderen, dass saslfinger -c mit sagt, dass "SMTP AUTH can´t work"

Okay, ab hier seid ihr gefragt. Ich hoffe ihr könnt mir dabei etwas unter die Arme greifen.

So, saßen nun insgesamt 4 Stunden zu zweit an dem Problem und haben den Fehler nun endlich gefunden. Vor 2 Monaten habe ich etwas auf dem Server installiert, was sich mitunter in meinem Mailserver eingenistet hat. Da ich seitdem meinen Mailserver jedoch nicht neugestartet habe, gab es auch nie Probleme. Jetzt habe ich vor ein paar Tagen meinen Server neugestartet und somit wurde auch mein Mailserver neugestartet und dann begannen die Probleme... Mir wurde das ganze aber erst heute gemeldet.

Thread kann dann also geclosed werden...
