Over deze vertaling

Cisco heeft dit document vertaald via een combinatie van machine- en menselijke technologie om onze gebruikers wereldwijd ondersteuningscontent te bieden in hun eigen taal. Houd er rekening mee dat zelfs de beste machinevertaling niet net zo nauwkeurig is als die van een professionele vertaler. Cisco Systems, Inc. is niet aansprakelijk voor de nauwkeurigheid van deze vertalingen en raadt aan altijd het oorspronkelijke Engelstalige document (link) te raadplegen.

    Inleiding

    Dit document beschrijft hoe een e-mailserver op basis van de geolocatie kan worden geblokkeerd en geweigerd met behulp van Sender Group op de e-mail security applicatie (ESA) die is geïntroduceerd in AsyncOS 11.0.0-264.

    Voorwaarden

    Vereisten

    Cisco raadt kennis van de volgende onderwerpen aan:

    • ESR-configuratie van de afzendergroep en HAT-overzichtstabel.

    Opmerking: raadpleeg de ESA User Guide of de Online Help van de ESA GUI voor meer informatie.

    Gebruikte componenten

    De informatie in dit document is gebaseerd op de volgende software- en hardware-versies:

    • ESA, alle hardware en virtuele apparaten met AsyncOS 11.0.0-264 of nieuwer

    De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u de potentiële impact van elke opdracht begrijpen.

    Configuratie

    Via de GUI

    1. Klik op het tabblad Postbeleid.
    2. Selecteer in het gedeelte Host Access Table HAT - Overzicht,
    3. Zorg er vanuit de vervolgkeuzelijst luisteraar voor dat de juiste luisteraar op dit moment is geselecteerd voor configuratie.
    4. Klik in de onderstaande kolom Sender Group op BLACKLIST,
    5. Klik op de knop Verzender toevoegen.
    6. Klik op de optie Geolocation.
    7. Selecteer het land dat moet worden afgewezen door de BLACKLIST Sender Group.

    Als u klaar bent met het toevoegen van de items, klikt u op de knop Verzenden en klikt u op de knop Wijzigingen vastleggen om de wijzigingen op te slaan.
