Patrick I am sorry I may not have been clear. The email being attached is not and never was encrypted to me or anyone else. The email being sent, containing the attached email, is being encrypted with PGP/MIME. The recipient can decrypt the email they receive. The recipient can see there is a .eml attachment. Opening the the attached email it *appears* blank (see attached), but if you view the source of the attached email you can see the contents OK. If I do the exact same but send the email and attachment unencrypted to recipient they can view the attached eml with out problem.

I knew that this would be the immediate proposal ;-) That would be anything but trivial. The email is only attached at sending time by a low-level Thunderbird function; before that it's only a pointer to a mail (which does not even need to be downloaded while writing the message). In other words, Enigmail would need to make sure that the attached mail is downloaded while the mail is being written, and then the mail needs to be decrypted (which could trigger a request to enter a passphrase -- something we want to avoid during message composition), and re-packaged in a similar same way as the function "Decrypt to Folder" works (except that the target a file this time). And then, then attached mail needs to be replaced with the decrypted copy. Finally you have to make sure that sending the message is not possible before that's completed. And obviously, this should work for PGP/MIME and inline-PGP. It's not very surprising that this is not even implemented by Thunderbird for S/MIME. -Patrick signature.asc Description: OpenPGP digital signature ___ enigmail-users mailing list enigmail-users@enigmail.net To unsubscribe or make changes to your subscription click here: https://admin.hostpoint.ch/mailman/listinfo/enigmail-users_enigmail.net

When forwarding a PGP/MIME encrypted email as an attachment, then the email remains _unchanged_ by Thunderbird upon attaching it. That is, the attached email is still encrypted to yourself (and whoever else was on the recipients/sender) but likely not to the person to whom you forward the email. Consequently, the person who got the email from you cannot open it. If you want to forward a PGP/MIME encrypted email, you either need to attach it inline, or you need to create a decrypted copy of the mail, and attach that copy. -Patrick -Patrick signature.asc Description: OpenPGP digital signature ___ enigmail-users mailing list enigmail-users@enigmail.net To unsubscribe or make changes to your subscription click here: https://admin.hostpoint.ch/mailman/listinfo/enigmail-users_enigmail.net

I have seen this too but I considered it a separate issue. In the case you describe what I am seeing is PGP/MIME email decrypts I can see the body of email ok and I can see attachments are there but when I open it tells me they are empty. This is harder to work out as it is not every email with attachment only some. As work around if you click "forward" on email the attachment opens okay from the new compose window.
