    Hallo zusammen,
    ich bin nicht sooo der Linux-Guru und habe daher eine frage.
    Ich habe einen V-Server. Darauf läuft ein Apache-Webserver.
    Dieser ist in letzterzeit zeitweise nicht zu erreichen.

    Prozessor auslastung ist minimal. Speicherauslastung ebenso.
    Nun habe ich mir die logs mal durchgeschaut uns sowas hier entdeckt:

    Für micht sieht das so aus wie eine bruteforce attacke auf meinen Mailserver.
    Liege ich da richtig oder kann mir sonst jemand sagen was das genau ist?
     
    Wenn mein Beitrag dir geholfen hat, würde ich mich sehr über eine positive Bewertung oder ein Danke freuen
    Gruß Johannes

    Hmm scheint eher so als möchte sich einer am Mailserver (SMTP) authentifizieren und der Mailserver findet dein SASL Backend nicht.
    saslauthd scheint nicht zu laufen bzw passt was nicht mit Berechtigungen
