E-mail set up question

[hooterchacon]

I have an e-mail set up question for all you tp professionals who might be able to shed some light on this problem for me as i cannot figure it out. ok this is what happend, i had my yahoo e-mail set up on my phone and every time i tried to send a message it would give me a failure notice saying pretty much it wasnt connected and when i checked my set up options my password had changed to a lot of characters (dont know what they were cuz all the characters where stars) and i re put in my password and tried to send again and the same problem persisted so i deleted my e-mail and tried to set it up again and when i get past putting in my password and go to the next step the password was different again. So if any of you have come across this problem or know an answer it would be greatly appreciated. thanks.
