email - PHP mail function always returning false

Question

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.

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.

Answer 1

Always use SMTP Authentication for mail sending by using phpmailer. mail() is not allowed on some hosting side. Because of spaming.
