Hello all
acording to document exist on Cisco for
How do I blacklist or drop a sending domain using Incoming Mail Policy and Content Filter?
it is listed
From the Web GUI, choose Mail Policies > Incoming Mail Policy. Create a new Incoming Mail
Policy. You can label the policy, "Block-Sender-Domains." Select the "Sender" option and put in
the sender's email address or domain that you want to block. (e.g. user@example.com, user@,
@example.com, @.example.com)
I want to block domain but I need to understand what is the difference between
@example.com and @.example.com
what I think if I use @example.com this will block the following
user@example.com
but will not block
user@test.example.com
if I choose @.example.com
this will block
user@example.com and user@test.example.com
thanks in advance to confirm on that or advice for better understanding
