我用qt mobility 写了一个发送邮件的程序，但是在maemo平台的n900上调试时发不出去邮件，提示说ACCount ID is invalid，不知道该怎么修改，请各位能帮帮我，以下是我的关键代码：
void dialog2::SendEmail(){
QMessageService *messageService=new QMessageService;
// Create a new email
QMessage msg;
msg.setType(QMessage::Email);
msg.setParentAccountId(QMessageAccount::defaultAccount(QMessage::Email));
// Add required parameters
msg.setTo (QMessageAddress(QMessageAddress::Email,"zhangbo1417@gmail.com"));

msg.setBody(EmailBody);
msg.setSubject("SMS Backup");

//Send email message
if(messageService->send(msg)){
QMessageBox::information(0,tr("Success"),tr("Email sent successfully!"));
hide();
}
else QMessageBox::warning(0,tr("Failed"),tr("Unable to send Email!"));
}

已解决
