I have old pop messages that cannot be decrypted “The modification detection code (MDC) is missing …

I’m using OSX high sierra.

How do i configure mail to ignore or configure this ?

I expect decoded pop / gig messages

    I am still waiting for an answer.
    I'd pay for support, but as this problem is a showstopper there will be no deal unless this is solved.
    I do like GPGTool, but due to this problem it's not workable for me.

    Does that help?

    As said in that article :
    " We will also provide you with a workaround for GPGMail if necessary. " It is this solution i want . Not extract and decode in external program, then i need no GPGTools at all.

    I repeat : can i have help to get GPGmail to decode my legacy PGP coded mails ??

    No, this article tells how to fix GPGServices. It also says that
    there might be a solution for GPGMail :

    We will also provide you with a workaround for GPGMail if necessary.

    Decoding in external program can be done with many programs. But then i do not need
    GPGTools . Convince me that i can use GPGMail and i'm in!
