Introduction
The UCM uses SMTP to send the email out and is set to smtp.gmail.com:587
Each time you make changes onto the Email Setting, you have to re-enter the email authentication password or the UCM saves garbage.
Please change the DNS server to Google DNS (for eg. 8.8.8.8) under UCM's Web Interface > PBX Settings --> Network Settings --> Basic Settings.
IMPORTANT
Make sure you turn on Less Secure App Access in your Google Account.

You will obtain traffic between SMTP and DNS with UCM (192.168.0.160) from Ethernet Packet when sending emails.
OTHERS
Please remember that certain email servers might consider emails coming from MTA as spam.
Reboot the UCM each time you change the Mail type (Client/MTA)
