In-Line Signatures

Hi there,

In this post a request was made to add in-line signatures - however it was rejected as the user didn't really have a use case.

I would like this option to be available, as I am the victim of a corporate mail server that injects content into emails.

When the signature is appended as an attachment, verification fails as the server decides to inject an obnoxious footer.

If the command line option is still available, would it be possible to be told what it is as a quick fix?

    Hi Adam,

    when will those clients finally use the standard...
    but yes, the option is still available.
    I have to warn you though, this was added in a night session and is very experimental.
    Only text can be inline encrypted/signed, attachments are NOT supported.

    To enable this feature run this command in

    defaults write org.gpgtools.gpgmail UseOpenPGPInlineToSend -bool YES

    Restart Mail after that for the changes to be applied.
    From that point on all mails which are to be encrypted or signed will use the inline method.

    To revert this at a later point simply run the same command but this time with NO instead of YES.

    defaults write org.gpgtools.gpgmail UseOpenPGPInlineToSend -bool NO

    Again, restart Mail.

    Hope that helps.

    That's great, thank you - I much prefer the attachment style, but the powers that be think an unenforceable disclaimer is more valuable than having secure email.

    Ah the powers that be... don't we just love them?

    Are you all setup? Do you need further assistance?

    All the best,
