PHP 4.0 Bug #9258: Mail function hangs SMTP server

From: patrick@theinfobox.com Operating system: Windows 2000 SP1 PHP version: 4.0.4pl1 PHP Bug Type: IIS related Bug description: Mail function hangs SMTP server I installed PHP 4.0.4pl1 as ISAPI filter on my system (Win2K SP1, IIS 5, and Exchange Server 2000). Everything seems to work fine except that if I try to send an e-mail with PHP, it will hang the IIS Virtual SMTP server. I am then unable to stop/restart the service and the only solution is to reboot. The only scripts I am using are from a standard PHP-Nuke install. In my php.ini, I have set the SMTP server to localhost, my IP, and my DNS name, but still have the same results. So far I have not been able to test it with an external SMTP server, but I am building one today for this purpose. -- Edit Bug report at: http://bugs.php.net/?id=9258&edit=1
