PHP mail stopped working

Viewed 83 times

Some days ago when using mail() I had it working.

But now it doesn't work. And I don't know what the problem is.

$to      = 'testmail@gmail.com';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: sender@gmail.com' . "rn" .
    'Reply-To: sender@gmail.com' . "rn" .
    'X-Mailer: PHP/' . phpversion();

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

$mail_sent = @mail( $to, $subject, $message, $headers ); 
echo $mail_sent ? "Mail sent" : "Mail failed";

It displays "Mail sent".

I haven't touched anything in Apache or this code. I have tested the code in an empty PHP file with the same result. How can I debug this problem?

Could it be that E-Mails are being sent fine, but are caught by a spam filter? If this could be, allow me to cross-post myself:

A few bullet points (Assuming that mail() returns true and there are no errors in the error log) :

Does the sender address ("From") belong to a domain on your server? If not, make it so.
Is your server on a blacklist (e.g. check IP on spamhaus.org)? This is a remote possibility with shared hosting.
Are mails filtered by a spam filter? Open an account with a freemailer that has a spam folder and find out. Also, try sending mail to an address without a spam filter.
Do you possibly need the fifth parameter "-f" of mail() to add a sender address? (See mail() command in the PHP manual)
If you have access to log files, check those, of course, as suggested above.
Do you check the "from:" address for possible bounce mails ("Returned to sender")? You can also set up a separate "errors-to" address.

For german speakers, I have written a quite exhaustive "what to do" on this issue some time ago. See here.

You have $headers .= '...'; followed by $headers = '...';; the second line is overwriting the first.

Just put the $headers .= "Bcc: $emailListrn"; say after the Content-type line and it should be fine.

On a side note, the To is generally required; mail servers might mark your message as spam otherwise.

$headers  = "From: no-reply@thepartyfinder.co.ukrn" .
  "X-Mailer: phprn";
$headers .= "MIME-Version: 1.0rn";
$headers .= "Content-Type: text/html; charset=ISO-8859-1rn";
$headers .= "Bcc: $emailListrn";
