apache - PHP xampp mail() function not working

Question

I am trying to send emails from my gmail account using php (xampp). I search over stackoverflow and as I got the things I changed my xampp's files sendmail.ini and php.ini as,

In C:xamppphpphp.ini I removed the semicolon from the beginning of the line extension=php_openssl.dll to make SSL working for gmail for localhost.

in php.ini file under [mail function] I changed

SMTP=smtp.gmail.com
smtp_port=25
sendmail_from = [email protected]
sendmail_path = ""C:xamppsendmailsendmail.exe" -t"

Then in C:xamppsendmailsendmail.ini. I replaced all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=25
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

then I wrote a simple mail function

<?php
$to = '[email protected]';
$subject = 'Test email'; 
$message = "Hello World!

This is my first mail."; 
$headers = "From: [email protected]
Reply-To: [email protected]";
$mail_sent = @mail( $to, $subject, $message, $headers );
echo $mail_sent ? "Mail sent" : "Mail failed";
?>

then went on the this page by my browser, got echo as Mail Failed.

I saw my debug file and I got

I am not getting whats the problem.

Answer 1

Ok, I got this working. Unfortunately not with TLS, because Port 587 is blocked in our network so I had to use Port 465. But I expect that TLS will also work.

I used XAMPP 5.6.3.

Sendmail config:

[sendmail]
smtp_server=smtp.gmail.com
smtp_port=465
smtp_ssl=auto
error_logfile=error.log
debug_logfile=debug.log
auth_username==*****@gmail.com
auth_password=*********
force_sender=*****@gmail.com

PHP config:

[mail function]
SMTP=smtp.gmail.com
smtp_port=465
sendmail_from = *****@gmail.com
sendmail_path = ""c:xamppsendmailsendmail.exe" -t"

Code:

<?php
$to = '[email protected]';
$subject = 'Test email'; 
$message = "Hello World!

This is my first mail."; 
$headers = "From: *****@gmail.com
Reply-To: *****@gmail.com";
$mail_sent = @mail( $to, $subject, $message, $headers );
echo $mail_sent ? "Mail sent" : "Mail failed";
?>

Important:

You will need to enable SMTP access in GMAIL, also you need to allow unsecure clients:

Be aware that the smtp port you want to use is open in your firewall! I suggest to try a connection check from your dev machine with thunderbird. Then you know if the client is able to connect.

This is my result:
