the email could not be sent. possible reason: your host may have disabled the mail() function.

• WordPress is built on PHP and it uses PHP mail() to send emails in different situations.
• It is also referred as wp_mail() function or just mail() function.
• PHP mail() function however, uses a program called sendmail to work or send email using sendmail_path.

your host may have disabled the mail() function.

• To find out if PHP mail() function is disabled in php.ini file, you need to first open the php.ini file. php.ini file is often located in a folder under /etc/php/.

possible reason: your host may have disabled the mail() function.

There are two conditions. $messagehave to be true (not an empty string, not false, not null, etc). And wp_mail() shouldn't return false.

			
					if ( $message && !wp_mail($user_email, $title, $message) )

			
	

			
	
			

		
	

You can easily find the path of PHP.ini file by uploading a simple php file with following script to your hosting server.

			
					<?php
   phpinfo();
?>

			
	

			
	
			

		
	

Word-press used wp_mail() function to send email which need PHPMailer class which used php mailer stored in /usr/sbin/sendmail.

Use this simple php function first to check php mail

			
					<?php
$to = "example@gmail.com";
$subject = "Test Email Function";
$txt = "Hello world!";
$headers = "From: webmaster@example.com" . "\r\n" .
"CC: xyz@example.com";

mail($to,$subject,$txt,$headers);
?>

			
	

			
	
			

		
	

If this is not working then you need to install php mailer. Use this command to install php mail on Ubuntu server.

			
					sudo apt-get install sendmail

			
	

			
	
			

		
	

Then check word-press email functions.
