On CentOS 7 server, PHP mail() function did not sent email. It always returned false.
I used following test script to verify mail is working
[root@server1 ~]# cat /var/www/html/1.php
<?php
$result = mail("[email protected]","testing","testing");
var_dump($result);
echo "mail sent at " . time();
[root@server1 ~]#
I checked the mails server log, found following error message
[root@server1 ~]# tail /var/log/maillog Oct 3 02:38:01 server1 postfix/postfix-script[28680]: starting the Postfix mail system Oct 3 02:38:01 server1 postfix/master[28682]: daemon started -- version 2.10.1, configuration /etc/postfix Oct 3 15:50:04 server1 postfix/sendmail[1515]: fatal: Recipient addresses must be specified on the command line or via the -t option Oct 3 15:50:25 server1 postfix/sendmail[1522]: fatal: Recipient addresses must be specified on the command line or via the -t option Oct 3 15:50:50 server1 postfix/sendmail[1570]: fatal: Recipient addresses must be specified on the command line or via the -t option [root@server1 ~]#
Problem fixed by adding proper sentmail path in php.ini
sendmail_path = /usr/sbin/sendmail -t -i
Here is config from the server.
[root@server1 ~]# cat /etc/php.ini | grep sendmail ; http://php.net/sendmail-from ;sendmail_from = [email protected] ; For Unix only. You may supply arguments as well (default: "sendmail -t -i"). ; http://php.net/sendmail-path sendmail_path = /usr/sbin/sendmail -t -i ; to the sendmail binary. These parameters will always replace the value of [root@server1 ~]#
