Smart P7M Support Description

Smart P7M Support is a Thunderbird extension that handles P7Mattachments. Smart P7M Support is a Thunderbird extension - build after lots of tests - that can "unhide" and handle P7M attachments.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.In theory, Thunderbird should automatically verify signatures and show attachments in positive case; if the verify fails, attachments are hidden.Unfortunately this verify seems not work properly in some cases, even if you import new certificates.How to Install in Thunderbird;1. Right-click the link below and choose "Save Link As..." to download and save the file to your hard disk.2. In Mozilla Thunderbird, open Add-ons from the Tools menu.3. Click the Install button, and locate/select the file you downloaded and click "OK". Requirements: · Mozilla Thunderbird What's New in This Release: · The extension now can handle also messages without "Content-type" in headers.
