<ref>http://serverfault.com/questions/215388/how-to-configure-sendmail-to-relay-through-a-specific-server</ref> Looking in the /etc/mail/sendmail.mc file add a smarthost entry that looks like the following
<br>
define(`SMART_HOST', `insidemail.tld')dnl
I had to use a fqdn and a host entry to resolve it with. There is a way to use an IP but I have not spent enough time working on this. Just needed it to send mail internally for now.
