【问题描述】：

我在 CodeIgniter 中设置了以下代码以使用 SMTP 发送电子邮件。

$config['protocol'] = 'smtp';
$config['smtp_host'] = 'send.one.com';
$config['smtp_user'] = '<MYEMAIL>';
$config['smtp_pass'] = '<MYPSSWD>';
$config['smtp_port'] = '587';
$config['smtp_crypto'] = 'tls';
$config['mailtype'] = 'text';
$config['crlf'] = '\r\n';
$config['newline'] = '\r\n';
$this->email->initialize($config);
$this->email->from('<MYEMAIL>', 'Test mailservice');
$this->email->to('mytestemail@gmail.com');
$this->email->subject('Email Test - ROLO ');
$this->email->message('Testing the email class.');
echo $this->email->send();

与 SMTP 的连接没有问题，我没有收到任何错误。但是电子邮件没有发送到 mytestemail@gmail.com，过了一会儿我在发件人地址的收件箱中收到了一条错误消息。交付状态报告：

Reporting-MTA: dns; mailrelay3-4.pub.mailoutpod1-cph3.one.com

以及以下（未传递的消息标头）：

我也遇到了同样的问题。经过大量试验和错误后，我发现在初始化电子邮件配置后添加以下行解决了我的问题：

$this->email->set_newline("\r\n");

希望对你有帮助！
