< p > iRedMail will store configrations in file iRedMail-x.y.z/config during
installation, and ask you whether to use it for installation directly
or create a new one.< / p >
< p > You can create a sample config file by executing iRedMail installer:< / p >
< pre > < code class = "bash" > # bash iRedMail.sh
< / code > < / pre >
< p > After config wizard dialogs, you will find file < code > config< / code > under iRedMail root
directory. For example, < code > /root/iRedMail-0.8.7/config< / code > . it will ask whether to
start installation or not, you can cancel it if you want.< / p >
< p > You can copy this config file to deploy as many servers as you want, change
the hard-coded passwords in it if you want.< / p >
