Message Filter Actions
Warning
The
Bcc()
,
notify()
, and
bounce()
filter actions can allow viruses through your network. The blind
carbon copy filter action creates a new message which is a full copy of the original message. The
notify filter action creates a new message that contains the headers of the original message. While
it is rare, headers can contain viruses. The bounce filter action creates a new message which
contains the first 10k of the original message. In all three cases, the new message will not be
processed by anti-virus or anti-spam scanning.

action multiple times:

The bcc-scan() Action
The
bcc-scan
action functions similarly to the bcc action, except that the message that is sent is treated
as a brand new message and is therefore sent through the entire email pipeline.
Quarantine and Duplicate Actions
The
quarantine(‘quarantine_name’)
action flags a message for inclusion into a queue called a
quarantine. For more information about quarantines, see the “Quarantines” chapter. The
duplicate-quarantine
(
‘quarantine_name’)
action immediately places a copy of the message into the
specified quarantine and the original message continues through the email pipeline. The quarantine name
is case sensitive.
