I'm not sure what you are doing but I am fairly sure you aren't doing the
right thing.  LISTSERV does not send an email confirmation of changes to
template messages.  

Assuming you are using the WWW interface 15.0 or later

 List Manangement > Customization > Mail Templates

On this page enter the template name to search for:  CONTENT_FILTER
 click on the 'Search' button.

The order of precedence highest to lowest:

 listname.MAILTPL  (if exists)
 language.MAILTPL  (if exists, this is not common)
 site.MAILTPL      (if exists)
 default.MAILTPL    required file, must exist

It is always a good idea to have a test list that you use to test any changed
settings or new content_filter before you apply them to the site-wide level.
