When you started with your Yahoo mail, you set up your account. And part of that setup is determining how your name should show up as a sender in the mail (for example, "Red Killian" or "Killian Red" or "Reddie"; just guessing of course).
Now go back to that setup screen and make it as you wish again.
I have spent hours looking for info on this and cannot get any answers. I returned from Vacation and found my sent Yahoo email shows up to recipients as false instead of with my email name. I used a different computer while on vacation to access my email, and when I came home I found that the FALSE was added.
Many of my friends/family is deleting my emails because of this. False shows up as Me, and not my name....please help...
I am running XP on a HP Pavilion m7590n
I have no other problems with my computer. I do clean it up and a few months ago did a defrag.
