& kmail; tries to save your mail to ~/ dead. letter in case of a crash. The next time you start & kmail; the mail composer should appear with your mail again; If it does not, try to open ~/ dead. letter with an editor. If it does not exist then the crash was so bad that & kmail; could not save your mail.
O & kmail; tenta gravar o correo en ~/ dead. letter en caso de o programa morrer. A próxima vez que inicie o & kmail;, o compositor da mensaxe debería aparecer de novo coa súa mensaxe; se non o fai, tente abrir ~/ dead. letter cun editor. De non existir, o fallo foi tan grave que o & kmail; non conseguiu gravar a súa mensaxe.
