Plaintext PGP signature support

Would it be possible to get support for the inline, plaintext PHP signature block? Look at the bottom of this e-mail to see what I'm talking about:

The detached signature is great, but I'd like the option to do the plaintext block as well. Thanks!

    Hi Major,

    there's a two reasons why we chose not to support the creation of PGP inline processed messages.

    The first and most important reason, Inline PGP was never defined as a standard as opposed to PGP/MIME. That's why there are a lot of different implementations out there and makes it a serious pain in the ass to already support Inline PGP decoding of messages. Most clients only support a small list of features of Inline PGP.
    We decided not to encourage the use of an old and outdated method for encrypting/signing mails with PGP and rather stick with the standardized PGP/MIME method.

    The second reason is the nature of GPGMail 2.0 for Lion being a complete rewrite of the plugin. We're a very small team with very little time at hand and didn't want to "waste" our valuable time on that feature.

    However, as I already suggested on Twitter, in a night of coding I've hacked very experimental support of creating PGP Inline messages into GPGMail.
    Signing/Encrypting of plain text is supported, attachments are not.

    To enable PGP Inline support run the following command in

    defaults write org.gpgtools.gpgmail UseOpenPGPInlineToSend -bool YES

    After running the command restart and you'll be able to send PGP inline messages.

    If you want to disable it again, run the command again and change YES to NO

    Hey Luke,

    Thanks for the quick reply! I wasn't aware of the issues with inline PGP signatures. I can see why you might not want to include it in GPGMail now.

    I'll give this a try and see how it works out but after reading what you said, I might be back to the PGP/MIME functionality pretty quickly.

    Thanks again. I'll be sure to send a donation your way shortly.
