I tried an experiment or two to try to duplicate your issue.
First I composed an email to two users, putting both of their addresses in the TO: field. Note that I had a PGP key for one user, but no key for the other. I selected "Encryption ON" on the Composition Toolbar. Enigmail refused to send the email, complaining about the lack of a key for the one user without a key. I repeated the experiment using BCC: for both users. The email was not sent due to the missing key. I put the user with no key in the BCC: field and the user ID with a key in the TO: field. Nothing, due to the missing key. I put the user with a key in the BCC: field and the user with no key in the TO: field. Enigmail refused to send it due to the missing key. The I repeated my experiments using Per-Recipient Rules. I defined rules for the two users. No matter what I tried, I could not get Enigmail to send the email - encrypted to one but not encrypted to the other. I chose Encrypt for the user with the key and no encryption for the user for whom I had no key. Nothing. In my opinion, this SHOULD work ...but it does not appear to be possible. The last time I use PGP (now called Symantec Encryption Desktop), it was possible to send an email to several people each with different encryption and signing settings. For example, if I sent an email to three people using PGP, I might specify the following settings: Encrypt-PGP/MIME and Sign for User-One, Encrypt-PGP Partitioned and no signature for User-Two, and no encryption and no signature for User-Three. In the background, this would result in three SMTP sessions, each sent to a different SMTP RCPT TO address. (See RFC 5321.) In effect, the email is sent three times. The requested encryption and signing settings are applied to each email according to the previously chosen selections. Of course, any address in a BCC: field would not be listed in the To: field of the RFC 822 header. Chris, I know that I haven't really solved your dilemma. Sorry. Enigmail engineers, got any thoughts? I'd like to be able to do what Chris is trying to do too. _______________________________________________ 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
