What should I do if the mail function in PHP fails to send emails?

mailfunction in php is a built-in function for sending emails, but if you really want to use the mail function to send emails, you must give your systemInstall the sendmail component. Now I encountered the problem that mail cannot send emails. Let’s take a look at the solution.

The previous server was transferred here Later, I found that the website could not send emails using mail(), but I found that sendmail has been installed. If sendmail is not installed, it can be executed. The code is as follows:

yum install sendmail

By the way, the host name must be set in a domain name format, for example :jb51.net, otherwise it will take a long time to start up when you restart sendmail, otherwise you will have to wait a long time. The code is as follows:

hostname .net

Then check whether sendmail is running normally. The code is as follows:

service sendmail status

If it is not running, it can be started. Change status to start. Then, edit php.ini and create a phpinfo in the web environment, because I use lnmp.

vi /usr/local/php/etc/php.ini

and then search :;sendmail_path =, press i to edit, replace with:

sendmail_path = /usr/sbin/sendmail -t -i

The default of my system is:

sendmail_path = /usr/sbin/sendmail -t -i -f

This -f seems to disable the mail function. After removing -f The mail function returns to normal. Then, restart the PHP process, usually: service php restart. LNMP is: service php-fpm restart. Under Apache, it can be: service httpd restart

. Let me share with you a php script test code. The code is as follows:

<?php 
$send = mail(&#39;your
Email
@lisizhang.com&#39;, &#39;邮件标题&#39;, &#39;测试邮件内容，如果收到此邮件，表示mail函数成功启用！&#39;); 
if($send){ 
echo &#39;true&#39;; 
}else{ 
echo &#39;false&#39;; 
} 
?>

If the return result is false, it means that the email is sent. If it returns true, it means that the email is sent successfully.
