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.

Have you tried using a library like [PHPMailer](https://github.com/PHPMailer/PHPMailer)? — sundance, Jan 24 '14 at 19:10
Did you connect to your mail-server with `telnet` or similar to verify it is actually working and receiving mail? — grebneke, Jan 24 '14 at 19:12
@grebneke I checked it already. Its working with the webmail perfectly . — bytestorm, Jan 24 '14 at 19:15
@grebneke I can't find the mailserver log. I can't access /usr directory, error logs are usually there right. — bytestorm, Jan 24 '14 at 19:25
@Bishal: If you have ssh-access and can run PHP from the commandline, a last resort could be to use `strace` to run your script and see exactly what it sends to the mailserver and the response it gets. It's an advanced command so you need to read up on `strace` to understand what's happening. — grebneke, Jan 24 '14 at 19:31

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

Are you changing the From: attribute in the header?

Some ISPs will block your mail if you do that.
