Why doesn't the attachment icon show up in emails sent to me?
Since I installed Sierra, emails sent to me that include attachments don't display that there is an attachment in the "view attachments" column of Mac Mail. I have reset Mail, changed the view and even tried to rearrange the columns. I can still see emails with attachments that arrived before the Sierra install, but not any of the emails that arrived after that install. How can I see the attachment icon in recent emails?
