Description:
------------
On Windows 2003, default smtp server.
When I use the mail function, some target e-mail system say:
195.56.151.XX, OutboundConnectionResponse, 2007. 06. 18., 22:06:43, SMTPSVC1, AS, -, 312, 0, 47, 0, 0, -, -, 451 See http://pobox.com/~djb/docs/smtplf.html.,



Reproduce code:
---------------
$subject = "Elveszett jelsz?";
$headers = "From: ".$mail_pswd_from."\nX-FW-MailID:s6s06s9s80";
$row=mysql_fetch_array($result);
$to = $row['usr_email'];
$body = "Tisztelt ".$row[usr_lastname]." ".$row[usr_firstname]."!\nAz ?n jelszava: ".$row[usr_pswd]."\n\n?dv?zlettel,\nA S";
mail($to,$subject,$body,$headers);

Expected result:
----------------
The email bounce to the sender from some hosts. (like citromail.hu, vipmail.hu) with this error message:
http://pobox.com/~djb/docs/smtplf.html

Actual result:
--------------
When I replace all newline to CRLF, the mail went away without problem:


$subject = "Elveszett jelsz?";
$headers = "From: ".$mail_pswd_from."\nX-FW-MailID:s6s06s9s80";
$row=mysql_fetch_array($result);
$to = $row['usr_email'];
$body = "Tisztelt ".$row[usr_lastname]." ".$row[usr_firstname]."!\nAz ?n jelszava: ".$row[usr_pswd]."\n\n?dv?zlettel,\nA S";
$body = str_replace("\r\n","\n",$body);
$body = str_replace("\r","\n",$body);
$body = str_replace("\n","\r\n",$body);
mail($to,$subject,$body,$headers);

Hi,

This is not a bug of PHP. 

E-Mail being transferred between mail servers needs CrLf (\r\n) as EOL separator. The catch however is how PHP sends the mail to your outbound mail server. On windows you always need to separate mail headers and end of lines with CrLf as this is the standard windows EOL separator. On Linux this depends on the mail injector of your Mail Server. For instance qmail expects the EOL separator to be the same as the standard linux separator Lf(\n) and when sending the message outbound converts all these Lf's to CrLf. If you feed this script with CrLf you will send E-Mail messages having extra white lines.

If your PHP script does not send the message to a typical local mail injector but to a normal inbound mail port it will have to follow RFC's and CrLf will be needed again.

So depending on your setup you either need to send CrLf or Lf between lines.

It's a real bug. :-)
because when I use the mail function, the mail bounced from some server. It is bug.

Please try sending mail to this address:
ashutest(at)vipmail.hu

This server is not Windows server, and MUST sending mail to this server with CrLf.

Please read http://www.faqs.org/rfcs/rfc822.html


But, oK.
How to set up correctly php on windows?
In my php.ini I cannot see settings for CRLF:

[mail function]
; For Win32 only.
SMTP = mail.xxx.hu
smtp_port = 25

; For Win32 only.
sendmail_from = return(at)xxx.hu

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
;sendmail_path =



When I use Wordpress, the mails not sendig for some host. Same in phpNuke, etc... So I think, it's a bug in php mail sending function.

I'm an ISP, and my users's codes don't run corectly on windows.
In my language this means it is a BUG.
