Good right? no its not, 5 minutes later i get a message from a yahoo helper and he says that my message couldnt be sent because of some error. What do i do to let me send e-mails again? Someone please answer. Thanks you

• Answer:

  Does this do this with everyone you email OR just certain people?!? More than likely the person is behind a fire wall on their computer or there is something on there end that is keeping you from sending. It is most likely not your email acct you have to worry about it is theres. Are you using cuss words or inappropriate material in your emails?!? This could be why they are not going through. Example my bf's work email address has a very strong fire wall that does not allow emails with any form of cuss words through and other material as well sometimes.
