Hello,

Is there any other way to sign an email message using PGP which would make it a bit optically clearer in means
of the PGP signature not being displayed? The point is that once sending a signed email, it looks like bunch of weird looking character where it is difficult for the recipient to isolate the actual message.

Thanks in advance!

   Hi Jacek,

   unfortunately how the signature is presented depends almost solely on the receiving client.

   If you use GPGMail on 10.7 we automatically use the PGP/MIME standard which uses a detached signature which is added to the mail as a separate attachment.

   If you use Engimail with Thunderbird you can also force it to use PGP/MIME (it doesn't by default).

   Hope that helps.

   Also if you use GPGMail on 10.7 and receive a message which includes the signature in the Mail content, GPGMail strips it out for you.

   Thank you for your support, unfortunately I'm using GPGMail on 10.5.8 co it looks like not much can be done without prior system upgrade.

   Ah ok, that's a little unfortunate indeed. Due to the fact that Apple doesn't officially support plugins for Mail.app and hence doesn't provide an API for it, we've had to drop development for 10.5. We'll backport the new version of GPGMail for Lion to Snow Leopard though once we find time.

   What you still can do though is to set use PGP/MIME in your GPGMail Preferences in Mail.app. It will not strip out the signature for you but others will see your signatures as attachments and no longer embedded in the actual message content.
