Can I block all incoming attachments but still allow the
message through?
No. The message and the attachment are treated as a single unit by the email
security service.
What happens if a message has several attachments, but
only one triggers an attachment filter?
If only one attachment triggers a filter, Attachment Manager performs the
disposition of that filter on the entire message, including all of the other
attachments.
Why can I see a message in my user’s quarantine when it
should have been redirected to an administrator’s
quarantine, or blocked by Attachment Manager?
The email message contained a virus, and your virus disposition is set to User
Quarantine. Because virus scanning takes precedence over other filters,
messages with viruses are disposed of according to your virus disposition.
An alternative is to set your virus disposition to Delete.
For more information, see the Configure Virus Settings for an Organization
section in the chapter.
What do I do when I get an attachment disposition conflict?
If two or more attachments in the same message trigger a separate filter with
different dispositions (except Ignore), Attachment Manager places the message in
the designated quarantine for the Quarantine Redirect disposition. That way, the
administrator can review the message and decide what to do with it.
For example:
•
In this example, the executables and ‘mm’ files are set to bounce.
•
The compressed files are set to user quarantine.
•
When these configurations have a disposition conflict, the correct behavior is
files with disposition conflict should be directed to the Quarantine Redirect
account. A disposition conflict is:
•
When a message with an ‘exe’ file inside a zip file is filtered, it is being
sent to the Quarantine Redirect account.
•
When a message with a ‘mm’ file inside a zip file is filtered, it is being sent
to user quarantine.
