Status: Open

I suspect this may be the same bug mentioned in #31676. My best guess
is that this is related to multi-threading.

Here it is again, edited slightly
to run on a Linux machine so that

Concurrent requests to the script were
handled quite nicely. The huge difference
in this case is the Apache prefork MPM.

Is the mail() function sufficiently thread-safe under the Windows MPM
(for Apache)? I have to wonder if the two concurrent threads are
stepping on each other in their efforts to talk to the SMTP box.

To clarify, the bash snippet should read like this (see below). Line
14 contains the call to mail().
========================================
$ (curl "http://192.168.1.2/error.php"; &); (curl
"http://192.168.1.2/error.php"; &)

Description:
------------
Hitting this script with two concurrent requests causes a failure of
both, each reporting different errors.
$ (curl "http://192.168.1.2/error.php"; &); (curl
"http://192.168.1.2/error.php"; &)
$
Warning: mail(): SMTP server response: 503 5.0.0 foo.bar.com Duplicate
HELO/EHLO in C:\Program Files\Apache Group\Apache2\htdocs\error.php on
line 107
FALSE
Warning: mail(): Failed to Receive in C:\Program Files\Apache
Group\Apache2\htdocs\error.php on line 107
FALSE
$
Reproduce code:
---------------
<?
define('EXTRAHEADERS', "MIME-Version: 1.0\r\nContent-type: text/html;
charset=iso-8859-1\r\nX-Mailer: PHP\r\n");
define('MAILMSG',
"<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\">
<html><head><title>foo</title><style type='text/css'>
body {margin: 0; font-size: 10pt; font-family: sans-serif, arial;
color: #000000; background-color: #ffffff;}
</style></head><body><div style='font-size: 12pt; background-color:
#ffff00;'>" . date("Y-m-d H:i:s") . "</div>
random junk<br />" .
str_repeat("afhlkhsad;lfj;lkjsa;lfjasd;lkjf;lkjsad;lkfjsad;lkfjsad;lkfjasd;lfkjasd;lkfjsa;ldf<br
/>\n", 100) .
"</body></html>");
ini_set('html_errors', FALSE);
ini_set('SMTP', '10.1.2.3'); // valid address for a SMTP relay
ini_set('sendmail_from', 'foo <[EMAIL PROTECTED]>'); // fake
address
define('MAILTO', '[EMAIL PROTECTED]'); // something real
$retval = mail(MAILTO, 'foo', MAILMSG, EXTRAHEADERS);
echo ( $retval ? 'TRUE' : 'FALSE' ). "\n\n\n";
exit();
?>
Expected result:
----------------
If I run multiple concurrent requests, then I expect to get multiple
emails, one for each request.
Actual result:
--------------
The little shell command where I run two HTTP requests (using cURL in a
Cygwin bash) concurrently causes a failure of both, each reporting
different errors. It runs fine otherwise.
