String Lists





For instance, the test header :contains ["To", "Cc"] ["", ""] is true if either the To header or Cc header of the input message contains either of the e-mail addresses "" or "".

Conversely, in any case where a list of strings is appropriate, a single string is allowed without being a member of a list: it is equivalent to a list with a single member. This means that the test exists "To" is equivalent to the test exists ["To"].
