Since Godaddy is still only offering Debian 8 for their GEN4 Servers and LTS is over in two months of this posting, I had quite the ride updating and installing my system. Only snag I ran into was an intermittent issue sending emails. I could reply, but not compose. Then the very next day, I could compose but not reply. Truly a headscratcher. Godaddy support pages or their tech support will offer ZERO info on their SMTP Relay config requirements outside of a URL. So with a little patience and a lot of time, I figured out the optimal listener file to use. I am using the USA Relay, but I am sure this will work for other regions.
I am providing my installation steps from a fresh provisioned server with Debian 8 all the way to a completed system running Debian 9 with most plugins offered by the i-MSCP team installed and working as expected.
Anyway, I have a great running system and here is what I did ...
Upgrade Debian 8 to Debian 9
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
Edit Sources for upgrade to 9
sudo nano /etc/apt/sources.list
Change all instances of jessie to stretch, save, exit and continue with upgrade to 9
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
I took all maintaners versions and when completed, I did a manual reboot.
Once rebooted, you can run cat /etc/os-release to verify successful upgrade to Debian 9
Then I ran sudo apt-get autoremove to clean up some files
Setup i-MSCP:
Super Easy
Run the following commands:
cd /usr/local/src
sudo apt-get update
sudo apt-get --assume-yes --auto-remove --no-install-recommends dist-upgrade
sudo apt-get -y --auto-remove --no-install-recommends install ca-certificates perl \
whiptail wget
sudo wget https://github.com/i-MSCP/imsc…e/1.5.3-2018120800.tar.gz
sudo tar -xzf 1.5.3-2018120800.tar.gz
cd imscp-1.5.3-2018120800
sudo perl imscp-autoinstall -d
I chose not to install Bind for my install, since I am running on my domain registrars network, but chose the options you want and let the install script complete.
After successful installation, open a web browser and go to http://panel.yourdomain.com:8080
The first thing I always do is install LetsEncrypt Plugin which is as simple as uploading plugin and activating it.
Create SSL Certs for your Control Panel and Services located under the "System Tools - Let's Encrypt" tab in your control panel.
Log out and go to https://panel.yourdomain.com:4443 for your new secure connection and install the rest of your plugins and configure i-MSCP for your needs.
List of Plugins I use and the packages required prior to activation of plugins.

If you were lucky, you should have a working system at this point.
After setting up basics (reseller, customers, etc) use listener file 10_postfix_tuning.pl shown below with slight modifications to be able to send email through Godaddy's SMTP Relay. Some entries seem redundant, but didn't work reliably until I added everything shown in Example below.
Save 10_postfix_tuning.pl in /etc/imscp/listeners.d ..
Disable CronJobs plugin in Admin Control Panel ...
Run the following command:
sudo perl /var/www/imscp/engine/setup/imscp-reconfigure -danv
Let the script do its thing and you should be good to go. (Remember to enable CronJobs Plugin)
Example of what I used. Just change 'smtp_bind_address' to your servers public ip and/or the relayhost URL if located outside the United States.

I have been sending, replying and every other way email can fly that I can think of with no issues.
I hope this helps anyone who is stuck with Godaddy and having to update their outdated systems to run modern software.
As always, I want to thank the developers for a wonderful control panel and look forward to the future.
Have a great day!
