Sophos E-Mail Protection, Exchange und Strato Hoster

Benjamin Rommel

Hallo,

wir sind dabei einen neuen Exchange Server einzurichten. Wir nutzen eine UTM und möchten E-Mails von Strato abholen. Leider komme ich nicht mit der konfiguration zurecht.

Wir haben bei Strato eine Subdomain mit A-Eintrag auf unsere Sophos erstellt. (utm.unseredomain.com) Wir haben eine feste IP-Adresse die hier genutzt wird.

 

Weiterhin haben wir den MX-Eintrag auf den Host utm.unseredomain.com weitergeleitet.  Ist dies grundsätzlich richtig oder verfolgen wir den falschen Weg?

 

Wie muss die Sophos nun eingerichtet werden?



Vielen Dank im Vorraus

    Some hosting companies allow you to put a spam filter in front of them.   Others will detect an unauthorized forwarder and block your traffic because it violates SPF.

    Some may allow you to put a spam filter in front of them, but still allow traffic that bypasses your spam filter and connects directly to them.   In this case, the bad guys will learn to bypass your spam filter.

    You need a hosting service that will allow you to use a spam filter and require all traffic to flow through that spam filter to be accepted.   Ask your vendor.   If the vendor supports this configuration, any spam filter, including UTM, can be used.
