Problem with importier emails

Sometimes it works and sometimes it dosen´t and says that the email couldn´t be decoded.
What can I do?

Could you post a screenshot of the error message? Thanks!

Her comes the screenshot.

Is Quick Look able to display the email? Or Apple Mail? Most likely reason is that the required key isn’t available in the keychain.

Hi Christian, I don´t understand.
I´m using Apple Mail and drag an email into the SORTER of DT. Then comes the message.

The other way (pulldown menu in Apple Mail “Add to DT”) either dosn´t work.

But with Most email it works.

Thanks

Frank

Is Quick Look able to display the email after dropping the email onto the desktop? Or does it make a difference in DEVONthink after using View > Text Alternative?
