Unable to send email

just wondering,

Should I have used sytes.net as the domain in the config files instead of kevinsproject.sytes.net, as its a subdomain?

Thanks.

Then the answer would be no, you use the subdomain unless you want to purchase a real domain name. There isn't anything specifically wrong with using a sub-domain to receive mail.

I've changed the bind config file again, this time using this guide

What errors do you see when you say you can't send mail?

Take a look at this excellent write-up from Lhammonds on the configuration of DNS on Ubuntu and compare it with your configuration. The easiest thing to do for configuring DNS is to a) use a better DNS server (such as PowerDNS &MySQL backend) or b) use webmin to manage and configure DNS.
