php mail function can't send email

[colap]

I have installed ssmtp on debian.

/etc/ssmtp/ssmtp.conf looks like this below:

[email protected]
mailhub=smtp.gmail.com:587
#rewriteDomain=
hostname=mybox
UseSTARTTLS=YES
[email protected]
AuthPass=[mypassword]
FromLineOverride=YES

php mail function:

$to      = '[email protected]';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: [email protected]' . "\r\n" .
    'Reply-To: [email protected]' . "\r\n" .
        'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);

From apache error.log i get this message:

sendmail: Authorization failed (534 5.7.14 https://support.google.com/mail/answer/78754 nz12sm1965155pdb.49 - gsmtp

Which software is used to send mail with php for debian and windows?

 

1)sendmail

2)ssmtp

3)msmtp

sendmail is the default daemon for php on windows and unix based systems i recomend using it...
