About Attachment Manager
Use Attachment Manager to filter messages based on the size or file extension of
any attachments. Each of several filters can have its own disposition, or method of
processing filtered messages. For example, centrally quarantine messages with
attachments that are .exe files, and you can user quarantine attached image files.
Attachment Manager can also send notifications to administrators or users when
messages are either bounced or redirected to an administrator’s quarantine.
When Attachment Filters Apply
Attachment filters are applied after all other filters except the Early Detection filters
(which send messages to the Pending tab in the Message Center). As a result:
• Attachment filters override content filters.
If a message triggers an attachment filter, it can be bounced or quarantined,
even if it contains content specifically allowed by a Content Manager filter.
• Approved senders can optionally bypass attachment filters.
If a message triggers an attachment filter that would bounce or quarantine it,
but it’s also from an org-level approved sender, it can still be delivered, if you
configure Attachment Manager to allow email from org-level approved
senders to bypass attachment filters (see “Configure Attachment Manager” on
page 275).
