HTC Incredible :: How To Delete Recent Email History From Yahoo Account?

Does anyone know how to clear historical contacts from the Email application. I'm using yahoo, I don't have Gmail set up on this phone because yahoo is my primary email. I've sent emails to 3 wrong emails. For example JoeSmith@aol.com, JSmith@aol.com, JoeS@aol.com but really his email is JoeSmith@yahoo.com. Now everytime I go to send this person an email, all 4 emails come up, the 3 in history, and the 1 in his contact information. When I type in J in the email recipient, all 4 come up, 3 say "history" next to the line of the email. I tried to add those emails into the contact, and then delete the emails, but that doesn't work.

I've went to yahoo to see if those contacts are showing up in history and they are not, so I know the historical email history is on the phone only. I haven't found a way to remove these items in history, but it's starting to cause problems because if I don't pay attention, I am choosing one of the wrong emails. Same thing is happening when I hit reply to ALL, 1 time about 2 months ago, and now i have about 40 emails in history and I don't even know who these people are, they are not in my contacts, and the phone is holding them hostage because I sent an email once. Does anyone know of a sure way to remove these historical emails?

If you don't know what I mean, give it a try, send an email to JOE@yahoo.com, and when you get it kicked back, the next time you try to send an email and hit "J", that JOE@yahoo.com will show up every single time, without fail. I've checked all historical settings on the phone, and even removed and re-added the yahoo account, but it does no good, the historical emails still stay in history. It's getting very annoying to have 45+ emails that you dont even know show up everytime you try to email someone something. Someone must have an answer for this, I can't be the only one that has sent the wrong email to someone.
