Die Liste kann Fehler in der Sortierung enthalten.
Es zeigt aber eine grobe Übersicht aller am Server geblocken Mailserver Angriffe und deren Herkunftsländer auf.


Jeder soll sich seine eigene Meinung darüber bilden. 
Natürlich ist es möglich Proxy Server zu nutzen um seine IP Adresse zu verschleiern oder über ein Botnetzwerk Angriffe auszuführen.
Also sollte man nicht alzuviel Gewicht in so eine Übersicht legen.

Wenn man eine grobe Vorfilterung je nach Land anstelle einzelner Blockirungen ganze IP Adressbereiche durchführen will, muss man das bei der Synology über eine Firewallregel durchführen.
