I only tried sending only just a few messages at a time. My earlier remark about "serious volumes" isn't what this bug report is about, it's about being able to send MORE THAN JUST ONE at a time without it stumbling all over itself. My testing used EXACTLY TWO concurrent attempts. Please re-read my remarks about execution under the Apache WinNT MPM. Is the mail() function thread-safe? Previous Comments: ------------------------------------------------------------------------ [2007-01-07 05:01:48] [EMAIL PROTECTED] Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. It sounds like SMTP server flood limiter is being triggered here. Not a PHP issue. ------------------------------------------------------------------------ [2006-11-20 19:42:15] rherror404 at gmail dot com I have found a work-around (not a fix). Do not rely upon the current mail() (at least under the Apache WinNT MPM) to be of any use for the case where more than one mod_php script is forwarding a message to an SMTP relay host. Have the mod_php script spawn a child process that takes a bit of serialized state via its STDIN and let the new process do the mail() work. See the proc_open() docs. If you have serious volumes of mail to send, either do it from a Linux box or find some other way to do it from your Windows box. Calling mail() under Windows/Apache/PHP for anything close to that (as it stands) is not advisable. ------------------------------------------------------------------------ [2006-11-14 16:14:10] rherror404 at gmail dot com I suspect this may be the same bug mentioned in #31676. My best guess is that this is related to multi-threading. ------------------------------------------------------------------------ [2006-11-14 04:18:49] rherror404 at gmail dot com <? /* Here it is again, edited slightly to run on a Linux machine so that it has its local sendmail do the work. Concurrent requests to the script were handled quite nicely. The huge difference in this case is the Apache prefork MPM. */ 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") .

"\n\n\n"; exit(); ?> ------------------------------------------------------------------------ [2006-11-14 03:56:24] rherror404 at gmail dot com 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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
