Are you currently searching for an easy way to install IceWarp Business Mail Server on Linux, preferably a Debian-based distribution? There's an easy way to automate that! I've written this awesome script in less than one hour:
#!/bin/bash
# IceWarp Download And Deployment Script
# Created by Bart Simons, 2016
# Dependencies:
# - wget
# - pv
echo "Downloading IceWarp..."
wget http://www.icewarp.com/download/server/Ubuntu/Ubuntu16/icewarp11/IceWarpServer-11.4.5_UBUNTU16_x64.tar.gz -q --show-progress -O icewarp.tar.gz
echo "Creating working directory..."
mkdir icewarp
echo "Extracting IceWarp..."
pv icewarp.tar.gz | tar -xzf - --strip-components=1 -C icewarp
echo "Changing directory to working directory..."
cd icewarp
echo "Executing installer..."
./install.sh
echo "Removing installation files..."
cd ..
rm icewarp.tar.gz
rm -rf icewarp
echo "Done!"
This should work, good luck with your brand new IceWarp installation!
