Mystery Solved! -- Why Some Of My E-Mail Ends Up In Spam Folder -- September 18, 2020

Was it something I said? See this note.

Apparently Yahoo!Mail is now directing much of my incoming e-mail to my "spam" folder if the incoming e-mail has an attachment from a "news" source or if the body of the e-mail contains a "cut and paste" news item. Apparently Yahoo!Mail is concerned that "news" attachments -- like news from The New York Times, the Washington Post, etc. -- might have imbedded viruses. 

Wow. 

But at least it explains why a lot of my legitimate e-mail was ending up in the spam folder.
