Heres my planned network <a href="http://mvpbaseball.cc/ee3.jpg" rel="ugc">http://mvpbaseball.cc/ee3.jpg</a><br />
<br />
I bought the domain name dissolvedz.com through NameSecure. Instead of using their DNS servers, I plan to use my own DNS server (as shown in picture). &nbsp;so I will be hosting a website, and I will have an exchange server here.<br />
<br />
The mail server is for internal clients. When they are outside of the facility, they will use <a href="https://owa" rel="ugc">https://owa</a>&nbsp; to access their mail. <br />
Did I set everything up correctly? Should the mail server be placed internal? Or does it stay in the DMZ? &nbsp; (im kind of confused on the placement of the mail server)<br />
<br />
Thanks in advance

Placement of mail server (is mail relay server needed?)

Operating system security (OS security) is the process of ensuring OS integrity, confidentiality and availability. OS security refers to specified steps or measures used to protect the OS from threats, viruses, worms, malware or remote hacker intrusions. OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised, including authentication, passwords and threats to systems and programs.
