Thunderbird Digitally Signed Attachments

KB Home   |   Thunderbird Digitally Signed Attachments

In our Email to Print module, digital signature wrapping of a message confuses the program parser used to extract attachments.

If the message is sent with the attachments signed separately to the message, Papercut handles the attachment with no problems. However if it is signed as a whole (message & attachments together) then it fails. This is because it is then sent as a multipart attachment, which we do not handle currently.

We could improve this by handling the multipart and searching within the multi-part attachment, but multipart handling and searching is currently limited to a small number of clients.

The Vendor for Thunderbird email notes this at their website:
NOTE: PGP/MIME is only supported by a limited number of clients.

The workaround is to use any other email client, such as Gmail.
