After deploying four ODROID-U3’s into a production network, the model is discontinued.
So I have to move on to the ODROID-XU4.
This means no more updates on the U3 software.
I did manage to deploy a U3 for:
- Internal DNS
- External DNS
- LDAP slave
- Inbound Email Gateway
These will remain in production until I need to replace them.
I am now looking at the XU4 with the CloudShell for use as an Inbound Email Gateway.
The CloudShell allows me to connect a 2.5 inch HDD which I prefer for the email gateway. I could use the MicroSD card for the spool, temp, and log files but the HDD gives me a larger storage volume.
