Adding Applications to our Windows Environment (Email Server - hMail) Part 2 - Additional Settings

After installing our email application (hMail) we need to apply a few additional changes in order to be able to connect to that server. 

On the Administrative Tool, we will go to Settings > Advanced > IP Ranges  

Different IP ranges get different settings. We have two different range (the local server - My Computer and everything else - Internet) 

We will Remove the Internet and Add our Main Network Range (10.10.10.0/24): 10.10.10.1-10.10.10.254. We will call it Internal. 

If we get a closer look, we can see the connections allowed by our clients (SMTP, POP3 and IMAP), and the direction from/to emails are allowed. We will disable the Require SSL/TLS for authentication option.

Now we will update the DNS Records A record mail that points to our email server (10.10.10.1) and also select the PRT record to be created. 

Windows Firewall blocks any incoming traffic that doesn't match the allowed Inbound Rules. We will allow two Inbound Rules that allow TCP port 143 and 25. Check a previous post of how to create an Windows Firewall Inbound rule.

We will go to Utilities > Diagnostics and run a basic test

Select our domain from the drop down list. 

After pressing start the test will run.
We are getting MX record and Backup errors. 

We can create a local MX (Mail Exchanger) record on our DNS Server

Using the nslookup tool on any VM within our domain, we can confirm that that we can resolve the MX Record for theo.local

To confirm go to Utilities > MX-query and type the email address we created 

We can enable backup, on Utilities > Backup. We simply need to select a Folder and specify what we need to backup. 

Another useful option is to enable logs. This can be life saver when we try to troubleshoot basic issues. Again we can specify which logs we want to enable.
