Hello to everybody, i have installed Ubuntu Desktop 8.10 on my laptop at home with ADSL internet connection. What i need to install and how to configure to be able to send email from my laptop via PHP: <?php $to = "email@example.com"; $subject = "Test mail"; $message = "Hello! This is a simple email message."; $from = "firstname.lastname@example.org"; $headers = "From: $from"; mail($to,$subject,$message,$headers); ?> I have read that i can do it with postfix, how i will install this and configure to be able to send email via PHP from my laptop at home ? I don't have a domain registered and i don't have an email address on my ISP and i have dynamic IP! I'm a beginer in Linux, so help me pls! Thanks!
