Mail function in PHP failed to send file resolution

Before that server transferred, found that the Web site with mail () sent to send mail. But found SendMail has been installed.

If SendMail is not installed, you can perform

The code is as follows	Copy Code
Yum Install SendMail

Yes, the host name should be formatted with a domain name. For example: sangsir.com
Otherwise, it will take a long time to restart the sendmail. (otherwise it will be a long wait)

The code is as follows	Copy Code
Hostname sangsir.com

Then see if SendMail is working properly.

The code is as follows	Copy Code
Service SendMail Status

Can start if it is not running. Status replaced by Start
Immediately thereafter, the editor php.ini. You can create a phpinfo in a Web environment
Because I'm using a lnmp.

Vi/usr/local/php/etc/php.ini

And then find:

; Sendmail_path =

By I edit, replace with:

The code is as follows	Copy Code
Sendmail_path =/usr/sbin/sendmail-t-I.

My system defaults to:

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

This-F appears to have the mail function deactivated, and the mail function has been restored to normal after the-F has been removed.

Immediately thereafter, restart the PHP process.

Generally: Service PHP restart
LNMP is: Service php-fpm restart
Apache can: Service httpd restart

To share a PHP script test code:

The code is as follows	Copy Code
<?php $send = Mail (' yourEmail@lisizhang.com ', ' message header ', ' test message content, if received, indicates mail function successfully enabled! ’); if ($send) { Echo ' true '; }else{ echo ' false '; } ?>

If the return result false indicates that the message sent failed, if TRUE indicates that the message was sent successfully!
