Zitat von Jörg

Hallo Michael,

die IP [203.43.245.10] blieb über den Tag dieselbe? um einen berechtigten User, der deinen Mailserver nutzen darf, handelt es sich wohl nicht? Möglicherweise handelt es sich um einen Spammer, der mit Brute Force Zugang zu deinem Mailserver erlangen will - aber wenn für Postfix keine schwachen Passwörter verwendet werden, sollte dies wohl nicht möglich sein.

Wie kann ich die IP sperren ???
iptables ? kennst du dafür ein HowTow?

Ist es nicht eher wahrscheinlich, dass er Username/Passwortlisten verwendet? Ich meine, ein BF-Angriff kann ja Jahrzehnte und länger dauern :))
