Ok i will do ny best to explain what is going on. I am running windows 2003 and IIS with microsoft exchange. and PHP 5.14. All are working well. I can send and recieve email from the exchange server with out a proplem. I have exchange setup so that only computers that are in a certain IP address can send mail, since I have not found a way to get PHP to authorize with exchange. I can not however send a form from the website. The form says it sent , but I never receive it. I have changed settings in the PHP.ini file from localhost to the ip that my server is on but no go. Here is how my current PHP.ini smtp settings. Any help would greatly appreciated. Thanks [mail function] ; For Win32 only.
