PHP Bug Type: Mail related
Bug description: Mail() hangs when sending large amounts of email
Description:
------------
When used repeatedly, in a loop, mail() will often hang causing the script
and/or browser to timeout. Sometimes the script will continue to execute
after the browser times out, causing all sorts of grief.
I've tested this on numerous (RedHat 7.x through RH FC1) servers, and have
seen the same issue since at least PHP 4.2.x.
(Just crossed my mind to report this as a bug!)
Reproduce code:
---------------
<?
set_time_limit(0);
$header="From: [EMAIL PROTECTED]";
$sql="SELECT email FROM list ORDER BY email ASC";
if ($res=pg_exec($dbconn, $sql))
while ([EMAIL PROTECTED]($res))
{
echo $row['email']."<BR>\n";
mail($row['email'], 'Mailing List News', $msg, $header);
}
?>
Expected result:
----------------
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
... 10,000 times.
Actual result:
--------------
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
... typically less than 100 times, and then browser times out.
