Enkelt PHP-script för kontaktformulär?

Hej undrar om det är någon som har ett bra php för en simpel kontaktform. helst utan spam. Har inte jobbat så mycket med php så tar gärna emot instruktioner hur man implementerar scriptet.

Tackar, Men har fortfarande problem att få det att fungera... när man trycker på skicka kommer man bara till felmeddelandesidan. Har provat en rad olika script men det är samma varje gång. Det verkar vara enkelt, men får det ändå inte att fungera. Jag lägger in formen i html:en och länkar till scriptet men fan det funkar inte.. hjälp mig?
