Griphon

Good Day All, I am very new to the php arena. I would please like some step by step assistance to setup a mailer for my local intranet(not hosted for internal use). If anyone has some advice I would appreciate it. I have searched the net, tried to load other code but get to the point where the feedback form will take me back to the home page but doesn't send the mail with no errors or warnings. Thanks in advance,
