Automated installation of Zimbra and Lets Encrypt update!

Previously we introduced the zinstaller script that can be used for automating the installation of Zimbra. The zinstaller script will install a Zimbra 9 single server on Ubuntu 20 and will also obtain and install a 60-day trial license. It now also supports automated installation of Zimbra with Let’s Encrypt certificates and it will take care of most of the Let’s Encrypt renewal process. You only need to schedule the Zimbra restart yourself!

If you are new to Zimbra, the zinstaller script makes it easy to evaluate Zimbra on premise. If you already run Zimbra you can use zinstaller to preview the latest features. Developers can use zinstaller as an easy way to set-up a development server.

Running the script

If your mail server is reachable under and you want your email addresses to look like, you can run zinstaller as follows:

wget -O /root/zinstaller
chmod +x /root/zinstaller
/root/zinstaller -p put-a-password-here -n mail -t 'Europe/London' --letsencrypt y

Having a poor connection over SSH? Try using screen:

apt -y install screen
wget -O /root/zinstaller
chmod +x /root/zinstaller
/root/zinstaller -p put-a-password-here -n mail -t 'Europe/London' --letsencrypt y

Should your connection drop, you can use the ssh command like normal and resume your session using:

screen -r

    Where is the capability to add LE support for already installed 9.0 single-server Zimbra?
    Simple cron script is preferred.

    It seems only port 25 is opened for SMTP, 465 should be also opened for smtps.
