Example 1
A message from sender
bill@lawfirm.com
sent to recipient
jim@example.com
will match policy #2,
because the user description matches the sender (
@lawfirm.com
) and the recipient (
ANY
).
Example 2
Sender
joe@yahoo.com
sends an incoming message with three recipients:
john@example.com
,
jane@newdomain.com
, and
bill@example.com
:
•
The message for recipient
jane@newdomain.com
will receive the anti-spam, anti-virus, outbreak
filters, and content filters defined in policy #3.
•
The message for recipient
john@example.com
will receive the settings defined in policy #5.
•
Because the recipient
bill@example.com
does not match the engineering LDAP query, the message
will receive the settings defined by the default policy.
This example shows how messages with multiple recipients can incur message splintering. See
for more information.
Example 3
Sender
bill@lawfirm.com
sends a message to recipients
ann@example.com
and
larry@example.com
