Why do I have to do the security code for every email I send. Friends of mine use yahoo and do not have this?

use Yahoo and do not have this problem. I cannot even contact family without doing a security code.|||Because Yahoo is doing a random security check on certain accounts. I was told that this will stop soon- I hate it too as it's happened to me as well. I would call or write Yahoo and complain about this to them or use google's email account which is much better anyhow- and it's FREE:)
