Hey everyone

We have been having a few issues in the household with xtra mail not sending on iphones, two different phones, two different xtra accounts with the same issue. Everything has been working fine until a few days ago with none of the settings touched, mail can still be received but no mail can be sent with the error "incorrect account name or password" coming up, reentering the password makes no difference. 

Both have been setup as per the instructions on telecom's website using yahoo tab in mail settings.

Any help would be much appreciated.
