[Thilo Engelbracht]

Hallo Liste!

Heute habe ich meine Postfix-Logdateien (z.B. /var/log/mail.log)
überprüft. Dabei bin ich auf folgende Einträge gestoßen:

Der Mailserver meines Providers empfängt E-Mails für meine beiden
Domains ("engelbracht.de" und "engelbracht.com").
Diese E-Mails werden mit "fetchmail" auf meinen Linux-Server übertragen
und an postfix übergeben.

Postfix lauscht - neben 127.0.0.1 - nur an der internen Netzwerkkarte.
Eigentlich sollte niemand von aussen auf den SMTP-Port zugreifen können.

Kann mir jemand helfen, die o.a. Logeinträge zu deuten?

Vielen Dank für Eure Mühe!

Gruß,

Thilo
