  9. On the text box on the Add Keyword Epression page, type a regular expression that will match any email address format that contains the keyword you want to filter in its username. Then click Save.
     
    Just like in wildcards, the "." is delimited by "\".

    For example, you want to detect emails that contain the keyword "bounce" in the username portion of the addresses, the regular expression would be:
