title: PHP mail function always returning false
body: <p>I want to send mails using php from my website. I have done the following steps but still the mail is not working. It is always returning a false.</p>
  
  <p>I have created a mail id and then has changed SMTP, smtp_port and sendmail_from values in php.ini file. I have tested setting the SMTP and smtp to both default values(localhost and 25) and the values given in mail client config of cpanel (abc-22.example.net and 465). I have also checked phpinfo to check whether those values were set successfully. I have checked the error log also, no errors logged there. The php version installed on server is 5.4.24.</p>
