Need assistance with Exim setup on 12.04

Hi all,

I am looking to get php mail() setup on my server and have tried following the Linode Exim guide (https://library.linode.com/email/exim/s … e-pangolin">https://library.linode.com/email/exim/send-only-mta-ubuntu-12.04-precise-pangolin).

Everything goes ok but when I test the setup using echo "This is a test." | mail -s Testing someone@somedomain.com (replacing the email with an email address I have) the email is not received.

Does anyone know what I might have done wrong?
