I have a friend who is signed up in a web hosting company, and he has his site uploaded and running for a couple of years... However, he recently decided to upgrade his site, and he had me design a contact form. I designed it, and it works OK in my server, but I can't seem to be able to run it from his server. I have reasons to believe that the company he is subscribed hasn't set up a mail server for him, in order to send mails using PHP. Can anyone tell me how can I do that? What do I need to know in order to manually set up a mail server in order to use PHP to send mails?
