PHP mail headers is not working properly

Question

I'm sending mails using the PHP mail() function. The mail headers is not working properly.

$charset = mb_detect_encoding($message);

$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'From: '.$from . "\r\n";    
$headers .= 'Content-type: text/html; charset='.$charset  . "\r\n"; 
$headers .= 'Reply-To: '.$from . "\r\n";
$headers .= 'X-Mailer: php';

In the above code, the only first line is parsed and the later 4 lines are showing in the message body. "From" was not set.

$charset = mb_detect_encoding($message);

$headers  = 'From: '.$from . "\r\n";
$headers .= 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset='.$charset  . "\r\n";
$headers .= 'Reply-To: '.$from . "\r\n";
$headers .= 'X-Mailer: php';

In the above code, "From" and "MIME" lines are parsed correctly, but the later 3 lines are showing in the message body.

GMail is receiving it correctly.

Answer 1

Have you tried to use \n only instead of \r\n?

http://php.net/manual/en/function.mail.php

Note:

If messages are not received, try using a LF (\n) only. Some Unix mail transfer agents (most notably » qmail) replace LF by CRLF automatically (which leads to doubling CR if CRLF is used). This should be a last resort, as it does not comply with » RFC 2822.

You may use the code below to easy change of end of line in email:

$EEOL = "\n";
$headers  = 'From: '.$from . $EEOL;
$headers .= 'MIME-Version: 1.0' . $EEOL;

You should consider using an email class library instead of the regular mail() function in php. I personally like the free SwiftMailer because of its simplicity and great functions for attachments etc.
