Email 在1和1主机上使用Codeigniter发送SMTP电子邮件

我正在尝试通过1和1上托管的codeigniter网站上的SMTP发送电子邮件。当我在本地执行此操作时，它工作得很好，但当我从我的1和1主机尝试时，我得到一个错误

这是我的配置：

$config['protocol'] = 'smtp';
$config['smtp_host'] = 'auth.smtp.1and1.fr'; //i'm in france and this is the SMTP server adress 1and1 gave me.
$config['smtp_port'] = 25;
$config['smtp_user'] = 'user@mydomain.com';
$config['smtp_pass'] = 'password';

$config['protocol'] = 'smtp';
$config['smtp_host'] = 'auth.smtp.1and1.fr'; //i'm in france and this is the SMTP server adress 1and1 gave me.
$config['smtp_port'] = 25;
$config['smtp_user'] = 'user@mydomain.com';
$config['smtp_pass'] = 'password';

下面是错误：

The following SMTP error was encountered: 110 Connection timed out
Unable to send data: AUTH LOGIN
Failed to send AUTH LOGIN command. Error:
Unable to send data: MAIL FROM:

from: 

The following SMTP error was encountered:
Unable to send data: RCPT TO:

to: 

The following SMTP error was encountered:
Unable to send data: DATA

data: 

The following SMTP error was encountered:
Unable to send data: //details about my message i removed
Unable to send data: .

The following SMTP error was encountered:
Unable to send email using PHP SMTP. Your server might not be configured to send mail using this method.

然后我尝试使用smtp.1和1.com而不是auth.smtp.1和1.fr。令人惊讶的是，它成功了，但执行起来却花了30秒！（在我的本地主机上，它是即时的）

有什么建议吗？

与他们的支持人员交谈。他们可能对港口有限制。或者使用sendmail。

如果您的托管服务器和电子邮件服务器位于同一位置，则不需要进行smtp身份验证

因此，请从配置文件中删除以下代码，将所有内容保留为默认值并执行您的功能。为我工作。在这种情况下应该对你有用
