The company policy is to prevent all users
from receiving Sound attachment types, but allow users
that belong to the Music Club receive mp3 files.
Solution:
Configure the Global rule to Block specified → Sound.
Create an exception rule that applies to Music Club.
Configure the exception rule target to mp3.
Typical User scenario II (AB Exception)
Scenario:
The company policy is to block .mp3, .doc,
and .exe files. However, allow the Music Club
to receive .mp3 files and allow ScanMail to receive .exe files.
Solution:
Set the Global policy to block .mp3, .doc,
and .exe files.
Create an exception rule named Music Club and
configure it to pass .mp3 files and set the
priority to 1.
Create an exception rule named ScanMail and configure
it to pass .exe files and set the priority
to 2.
Known Issue:
If a user belongs to both the Music Club and ScanMail groups, when
an email message includes .mp3, .doc,
and .exe files, the user will receive the .doc and .exe files.
