php contact form error

i don,t understand exactly what to do please explain to me i'm a beginner so tell me exactly what to do

do i have to change thelocalhost server

and what to do about second error

Comment out the "mail(..." line and the second error should go away and it should redirect you. You'll have to configure the SMTP on your local server for it to be able to send emails, or if it is already set alter the settings PHP has in the configuration file (php.ini).
