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 

edit-header-text 

action allows you to rewrite specified header text using the regular expression 

substitution function. The filter matches the regular expression within the header and replaces it with a 
regular expression you specify. 

For example, an email contains the following subject header:

Subject: SCAN Marketing Messages

The following filter removes the “SCAN” text, and leaves the text, “Marketing Messages”, in the header:

After the filter processes the message, it returns the following header:

Subject: Marketing Messages

The 

edit-body-text()

 message filter is similar to the 

Edit-Header-Text()

 filter, but it operates across 

the body of the message instead of one of the headers. 

The 

edit-body-text()

 message filter uses the following syntax where the first parameter is the regular 

expression to search for and the second parameter is the replacement text:

The 

edit-body-text()

 message filter only works on the message body parts. For more information 

about whether a given MIME part is considered a message “body” or a message “attachment”, see 

.

The following example shows a URL removed from a message and replaced with the text, ‘URL 
REMOVED’:

Remove_SCAN: if true

   {

      edit-header-text (‘Subject’, ‘^SCAN\\s*’,’’);

}

Example: if true {

edit-body-text("parameter 1",

"parameter 2");

       }

URL_Replaced: if true {
