我使用以下代码用于雅虎并且它不起作用，你能帮助我做错了吗？当我使用主机作为smtp的gmail时，相同的代码运行良好。我正在尝试使用yahoo，AOL，windows hotmail从本地服务器发送电子邮件。以下是在application / config文件夹中创建的文件，名称为email.php
$config['protocol'] = "smtp";
$config['smtp_host'] = "ssl://smtp.mail.yahoo.com";
$config['smtp_user'] = "myusername@yahoo.com";
$config['smtp_pass'] = "**************";
$config['smtp_port'] = "465";
$config['charset']="utf-8";
$config['newline']="\r";
$config['crlf'] = "\r";
