I realize this is a pretty specific question, but in my learning process it's an issue I've come across. This is part of a learning project for me.
What I have:
CentOS 6 virtual box
OTRS Ticketing system installed and browser accessible via IP
This ticketing system is on a box that is on our internal network.
I'm trying to set up sendmail to relay the ticket emails to our techs and to receive email notifications from Nagios in order to generate said tickets.
I have the email address created and I am able to send/receive emails from it from within Outlook on my work computer just fine. (email@example.com)
My question is really related the host name of the centos virtual box. Currently, my hosts file is as follows:
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
I'm at the point where I need to send in a ticket to our DNS server admin and have him make the necessary additions for this server to be able to use sendmail. However, I'm not certain if I need to change my hostname on this box? I'm not sure if setting the host name of this specific box to otrs.example.org is actually wrong? I'm a bit lost at this point (as if that wasn't obvious) and would appreciate any guidance that anyone might be able to provide.
