"p7m" attachments are files with a digital signature that confirms sender`s identity. Since Thunderbird considers just the attachment type (content-type), it`s more correct talk about attachments with type application/pkcs7-mime or application/x-pkcs7-mime.
Teorically Thunderbird should automatically verify signature and show attachments in postive case; if the verify fails, attachments are hidden.
Smart P7M Support extension goal is to improve P7M attachments support.
