The mbox format is a standard UNIX mailbox format, and there are many utilities available to make 
viewing the messages easier. Most UNIX systems allow you to type 
“

mail -f 

mbox.filename” to view the files. The mbox format is in plain text, so you can use a simple 

text editor to view the contents of the messages.

In the following example, a copy of the message is saved to a log named 

joesmith

 if the Envelope Sender 

matches 

joesmith@yourdomain.com

:

The 

strip-header

 action examines the message for a particular header and removes those lines from the 

message before delivering it. When there are multiple headers, all instances of the header are removed 
(for example, the “Received:” header.) 

In the following example, all messages have the header 

X-DeleteMe

 removed before transmission:

When working with headers, remember that the current value of the header includes changes made 
during processing (such as with filter actions that add, remove, or modify message headings). See 

 for more information.

The 

insert-header

 action inserts a new header into a message. AsyncOS does not verify the compliance 

to standards of the header you insert; you are responsible for ensuring that the resulting message 
complies with Internet standards for email.

The following example inserts a header named 

X-Company

 with the value set to 

My Company Name

 if the 

header is not already found in the message:

logJoeSmithFilter:

   if(mail-from == '^joesmith@yourdomain\\.com$')

   {

        archive('joesmith');

   }

stripXDeleteMeFilter:

   if (true)

   {

        strip-header('X-DeleteMe');

   }

addXCompanyFilter:

   if (not header('X-Company'))

   {
