Hello Leon,
I think I may have mentioned this before, but not sure, so I'll suggest it once again...
Why not give Mailwasher Pro a try?
I've been using it for many, many years & never had any kind of "nasty" on my system.
It just displays you the headers & allows you to "wash the mail" before D/L'ing to your device/s.
Take your time to read the links as to what it does.
Plus, it's available for any mobile device & complete instructions are provided at the bottom of the page...under "MAILWASHER MOBILE."

Hope this helps "The Missus" with her spam dilemma.
Stay safe.
Regs, Laurie..
