Skip Remaining Message Filters Action
The skip-filters action ensures that the message skips any further processing from message filters and
continues through the email pipeline. The message that incurs the
skip-filters action will be subject
to anti-spam scanning and anti-virus scanning, if it is available on the appliance. The
skip-filters
action is the default final action for message filters.
The following filter notifies
[e-mail] and then immediately delivers any message
addressed to
boss@admin.
Drop Action
The drop action discards a message without any delivery. The message is not returned to the sender, not
sent to the intended recipient, nor processed further in any way.

if(rcpt-to == 'boss@admin$')
