/usr/sbin/sendmail: not found error with PHPMailer

If you’ve stumbled into this PHP Mailer error when trying to send an email, this might be why…

I’m running a Ubuntu web server, and my PHP mail script was outputting this to my error logs:

sh: 1: /usr/sbin/sendmail: not found

What I didn’t realise is that I hadn’t already installed sendmail onto the Ubuntu web server. Doh! So the fix was as simple as logging into the server and installing sendmail with the following commands:

$ sudo apt-get update
$ sudo apt-get install sendmail

FYI, my PHP Mailer script looked like this:

$mail = new PHPMailer();

$body = 'An email test!';

$mail->AddReplyTo('abc@example.com', 'Clark Kent');
$mail->SetFrom('abc@example.com', 'Clark Kent');
$mail->AddAddress('me@example.com', 'Code Chewing Guides');
$mail->Subject = 'Test email';
$mail->MsgHTML( $body );

if( ! $mail->Send() ) {
  echo "Mailer Error: " . $mail->ErrorInfo;


If this was the simple fix for you too - happy emailing!
