I'm seeing exactly the same problem. I see this when composing eMails using my iCloud account - no Exchange involvement, strangely enough the complaint I'm seeing regards a different outdoing mail server - not the iCloud outgoing server. I have multiple eMail accounts and the account mentioned in the error messages is the only other account set up for GPG

    Hi Keith,

    welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.

    Could you please temporarily disable GPG Mail by de-selecting it in Mail › Preferences › General › Manage Plug-ins and then check if the problem is gone or if it persists.


    P.S.: We would kindly ask you to create a new discussion, whenever you need assistance with GPG Suite, even if your problem looks similar to the one you are replying to. While the symptoms are often very much alike, the root cause often differs. Having separate discussions allows to focus better on your particular issue.

    To proceed we have split your comment into a separate discussion.

    Thanks for your swift reply - subjective observation. I’ve been experiencing the same nagging error message whilst composing an eMail to a client and then whilst composing this reply to you. I suspect the message is generated when Mac OS Mail updates the eMail being composed as a draft. It’s an automatic process, without checking I can’t say what prompts the update. However, and this is another subjective observation it seems that the nagging dialog is only presented when the sign eMail button is live. If it’s turned off the dialogs stop being presented.

    Best Regards

    Hi Keith,

    excuse the long silence.

    A few more questions about this error message you are seeing:

    1. Have you updated to macOS 10.14.2 and does the problem persist with that macOS version?
    2. Your observation of this being related to the sign state of a draft is very interesting and you may be onto something here. What happens if you create a new draft, disable signing, compose your draft and before sending enable signing? Does that result in the error not showing?

    We have a ticket for this problem. I connected this discussion with the existing ticket. That means, should this discussion get closed, it will be re-opened as soon as the ticket is closed. That way you'll stay in the loop and get notified as soon as we have news. Feel free to open a new discussions should you run into further problems or need assistance.

    All the best,

    Oh and is there an Exchange Server involved in your email setup?

    And do you use the default to encrypt drafts (Mail > Preferences > GPG Mail > Encrpyt drafts)

    Could you play with that and see if that makes any difference?

    Sorry I’m unable to evaluate any of the suggestions because my GPG evaluation period has terminated. Given the problem experienced I wasn’t prepared to purchase a “support” package.

    Ok, makes sense. We are still investigating this specific issue which we never reproduced and affects a very small number of users.

    We'll keep you updated, if we have news regarding this problem.

    Have a nice rest of the weekend.
