In the email system I have on my website, I get loads of spam from fake emails because there isn't an email authentication set. How do I go about setting this up?

Are you refering to something similar to 'CAPTCHA' or a way to see if an email address exists?

CAPTCHA is later for me :p.. No I'm looking to see if the e-mail they provide currently exists.

You shouldn't ever require to actually validate on the users server whether the email exists or not. In fact, there may be valid configurations which will deny such probing, or reroute to specific addresses.
Your best bet is to simply send an email to the email address with a confirmation link. If the email does not exist, then no confirmation link.
Again, there are ways to circumvent this (by trapping all emails on said server into a single pipe), but then again you would still want to implement a captcha to reduce automated requests in general.

How would I go about implementing a captcha in because I want to eliminate the spam populating in my inbox and my guestbook from computer generated posts.
