Please help with testing a new
#Thunderbird #Security feature: Unobtrusive Signatures, a novel mechanism for digitally signing email, currently implemented for #OpenPGP.
It avoids the unexpected signature attachments that are shown by non-supporting email clients for emails that used the traditional signing format, and that were frequently confusing recipients. With this new mechanism, it should be fine to sign all emails.
