Have you tried just deleting the account, then setting it up again?

I have experienced the same thing, after being asked by bt yahoo (btinternet) to changed my password, I am no longer able to receive or send mail from my iPhone and iPad. However my other email accounts with other providers are not effected, as always the problem again is my btinternet account. Has anyone got a solution? It is very annoying.
