Everytime i send an email to myself, Harley09@myyahoo.com, It duplicates itself! This is using tons of storage plus its annoying bc it complicates my email if I wish to forward just one. This has been ongoing since i joined myyahoo.com mail. So i changed from the old yahoo to the new yahoo email service but it still doesnt the same thing so I changed back to the old email version but its still doing it. So i changed back to the new version. It took me forever to find ur mail SETTINGS. I had to do an online search. I also went online to find directions on what to do to STOP THE REDUNDANT EMAIL when i send. The online instructions r easy enough but when i go onto ur app on my Mac Air Laptop, None of the online instructions r to be found! JESUS! i should b able to end this issue but your email is NOT USER FRIENDLY for a lay person and a NON engineer!
