Alter Recipient Action
The 
alt-rcpt-to
 action changes all recipients of the message to the specified 
recipient upon delivery.
The following filter sends all messages with an Envelope Recipient address that 
contain 
.freelist.com
 and changes all recipients for the message to 
 
system-lists@myhost.com
:
freelistFilter:
   if(rcpt-to == '\\.freelist\\.com$')
   {
        alt-rcpt-to('system-lists@myhost.com');
   }
Alter Delivery Host Action
The 
alt-mailhost
 action changes the IP address for all recipients of the selected 
message to the numeric IP address or hostname given. 
Note
The 
alt-mailhost
 action prevents a message classified as spam by an anti-spam 
scanning engine from being quarantined. The 
alt-mailhost
 action overrides the 
quarantine action and sends it to the specified mail host.
        duplicate-quarantine('Policy');
        drop-attachments-by-name('(?i)\\.mp3$');
