Currently, I'm running Apache 1.3.26 with PHP 4.2.2 (and MySQL) on Windows 2k. I've downloaded Jack's Formmail script from http://www.lumbroso.com/scripts/formmail.php but have had no luck in making it work, even when I followed everything in the documentation. After doing a bit of research and asking around, I found the answer: Search for and open php.ini Find the following lines: [mail function] ; For Win32 only. on the next line - add your ISP's SMTP mail server to it: SMTP = smtp.virgin.net (the above mail server would only work if you was connected to Virgin.net, like I am. Just replace it with your own ISP's mail server address) This is how the finished result will look: [mail function] ; For Win32 only. SMTP = mail.domain.com
