Exim4 not sending mail if recipient is on the same domain as the website.
Exim seems to be "delivering" mail locally if the recipient is on the same domain as the webserver. How do I force exim to always send out the mail?

I was able to resolve this issue, I had inadvertently set the hostname to the domain name. Setting the hostname to:
something.domain.com and then reconfiguring exim fixed the issue.
