decrypting multipart/mixed messages

[Davide Cavallari]

Sorry if this is OT, however I don't know where to ask this. 

How can I decrypt a message directly in mutt, if its Content-Type header
is multipart/mixed?

I tried to comment the line:

* !^Content-Type: multipart/ 

in my  .procmailrc file,  but now both  original message  and attachment
(which is not encrypted) are put together in the same decrypted message.

Do you know the cleverest way to try?

Never use "etc." -- it makes people think there is more where there is not
or that there is not space to list it all, etc.
