If you have Windows, PHP can only use an extrenal smtp server, so you have to
open that server up to connections from your web server to your mail server. That could be on the same physical machine as your web server, in which case the mail server will have to be configured to accept connections from localhost. In this case, you use the SMTP and smtp_port paramaters, and the sendmail parameter is ignored. Questions: 1. What is an SMTP server? Does it come automatically with PHP or what? 2. What is my mail server, like AOL that I am using now or something else? 3. How do I make sure that my SMTP server is connecting to my mail server? 4. How do I make sure that/ configure it so my mail server is accepting connections from localhost? -Andrew
