Sendung a encrypted mail to a mailing list with multiple recipients.

The keys for all mailing list recipients are correctly configured in gpg.conf for the mailing list.

Mail is encrypted only for the first mailaddress of the list, all other recipients can’t decrypt the mail because of missing key.

Expected
Like in the previous versions for El Capitan: all mailing list recipients can decrypt and read the mail, all keys that are used in gpg.conf are used for encryption

    Hi Achim,

    this issue has been fixed. If you want to test the fix, please download our latest nightly GPG Suite. That page also has sig and SHA1 to verify the download.

    Seems to work, mailingslists are encrypted correctly.

    But I'm able to sign my mails no with this nightly build. :-( In a few weeks, macOS High Sierra is released and it doesn't work for Sierra for now... :-(

    Can you be more specific about the issue you are seeing?

    You write you cannot sign your mails? Could you please double check you have the latest nightly: https://releases.gpgtools.org/nightlies/

    1952n is the latest build as of 2017-08-28. You can check which build you have installed in System Preferences > GPGPreferences / GPG Suite.

    Looking forward to your feedback.

    Yes, I doublechecked this, I have GPG Suite 2017.1 (1952n) installed.

    I'm not able to sign my mails. Trying to sign my mails gets the error message "gpg: signing failed: No secret key".

    Encrypting works.

    That sounds like another problem then.

    First, let's check if your key is ok:

    1. open GPG Keychain
    2. double click your sec/pub key
    3. create a screenshot of the key tab (⇧⌘4 + drag w mouse)
    4. create a screenshot of the subkey tab
    5. attach both screenshots to your discussion by visiting it in your browser

    Should your key have expired, please re-new the expiration date in the key tab.

    To renew the subkey, open the subkey tab, click the cogwheel and change the expiration date

    After that send a signed and encrypted test mail to yourself. Are you able to decrypt and verify the signature successfully?

    In case your key resides on the public key servers, don't forget to upload your updated key, so that the changes are reflected on the key servers.

    Best regards,
    Steve
