Oh! Then I suspect the answer may be your list settings. I've seen 
cases where when MLMs like Mailman or Sympa are set to tamper with the 
MIME parts before delivery, they will sometimes end up scrubbing parts 
you don't want scrubbed. Like Sympa will scrub the text/calendar part 
of a multipart/alternative when you're just trying to get rid of an 
unwanted text/html part. Extra frustrating when the sending client 
fails to understand the meaning of "alternative" - hello Outlook - so 
the remaining text/plain part doesn't actually contain the details of 
the event.

Sounds here like Mailman is scrubbing the text/plain part for you, and 
leaving only the application/php-signature part, which certainly isn't 
much use on its own! The copy I received through the list had both, so 
our subscription settings probably differ.

Good, I'll try to remember switching it off for this thread.
