What do I need to do to set a SMTP on a PHP based comment form ???

I've got the form ready along with all the necessary field validation and everything.

Since I want to receive e-mail after someone presses "Submit" button, I would have to make some changes in "php.ini" file but I wonder in order to do so, would it make more sense if instead of using "localhost", I use the SMTP provided by some web host company (such as godaddy.com), something I could only get AFTER I sign myself up with them.

the problem is that you want to send an email to another server right? your page is on a server and must have it's own email serving program (daemon) running. I wondered this too and ended up installing sendmail on my linux box.

btw, if you didnt get that far, mail() is the php function you want to use.
