Could not execute mail delivery program

$this->load->model('emailmodel');
$query = $this->emailmodel->get_emails();
$emails = array();
set_time_limit(0);

foreach($query->result() as $u)
{
    $this->notification->send($u->to, $this->config->item('neworder'),'orders/mail/subscription', 
        array(
            'order' => $neworder,
            'user' => $user
        ));
    break;
}

so I am sending mail in a loop for each subscribed user, but it gives me an error:

Could not execute mail delivery program '/usr/sbin/sendmail -t -i '

how to fix this?

The same case of sending more than 50,000 emails (1.1GB of data) occurred here.

I used a simple script that reads everything with a "select * from email_queue" and passes it to mail() in a mysqli_fetch_assoc()-loop. This has been running smoothly with cronjob for years, but not the last times.

The solution here was to send only a "select id from email_queue", which then reads the record in the loop with another "select *..." and passes it to mail(). Besides, the average load has dropped significantly.

In my case the site was hosted on MediaTemple and it appeared to be the PHP version. The site was running on 5.3 FastCGI and when I switched to 5.3 CGI it worked fine.

We also had this strange error show up all of a sudden. Restarting php-fpm cleared the issue in our case. It may have been caused my the maximum number of files, or some other memory-leak type of issue. To prevent this from happening again, I enabled pm.max_requests = 200 so that the php-fpm processes are cycled more often.

We had the same problem. please check the security limits on your system (ulimit)

You can execute ulimit -a

bash# ulimit -a

...
open files (-n) 1024
max user processes (-u) 1024
...

You can change this on RedHat in /etc/security/limits.conf We have change the nproc and nofile to a bigger value.

Because each mail() call opens a port(file). If you reach the Filelimit this errormessage occurs.

I think your system doesn't support sendmail in that path.. You have to change the sendmail path or reinstall it and be sure that your queue mail isnot overloaded...
