I need to filter calendar events. All such messages have an attachment with Content-Type: text/calendar.

Here: http://forums.mozillazine.org/viewtopic.php?p=724059&sid=c5807de9790f2a3ac3c3ed36531297c4#p724059 I found that a body filter also applies to attacment headers.

I created a test filter "Body contains text/calendar" with the action to mark matched messages as unread. When I run the filter on my inbox, only some calendar messages are affected:

Here's an extract from a message that matches: 

   Content-Type: multipart/mixed; boundary="001a1144413e115b8c055e744899"
   ...    
   </span></span>
   </body>
   </html>
   
   --001a1144413e115b87055e744897
   Content-Type: text/calendar; charset="UTF-8"; method=REQUEST
   Content-Transfer-Encoding: 7bit
   
   BEGIN:VCALENDAR
   ...


And here's an extract from a message that does not match: 

   Content-Type: multipart/alternative;
   	boundary="_002_FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF_"
   ...

re : I created a test filter "Body contains text/calendar"

Suggest you try : 'Content-Type' 'contains' 'calendar'

I've just tested a filter using 'Content-Type' 'contains' 'alternative' which I ran manually on Inbox and everything was correctly moved as specified in filter.

Please note that filters run in the order listed, so if an email has already been filtered by another filter then it will not be able to filter as expected because email is not there.

This didn't work, because only the first occurrence of Content-Type is matched. Besides, the word "calendar" would give too many false positives. 'Body' 'contains' behaves differently for the two messages in my example. I can search the insights of the attachments in both of them, even though the second one is base64-encoded, but only in the first message I can search the attachment headers.
