 Assuming we are installing Postfixadmin into /srv/postfixadmin, then something like this should work. Please check https://github.com/postfixadmin/postfixadmin/releases to get the latest stable release first (the 3.2.10 version/url below is probably stale)
 
   $ cd /srv/
-  $ wget -O postfixadmin.tgz https://github.com/postfixadmin/postfixadmin/archive/postfixadmin-3.3.10.tar.gz

   $ tar -zxvf postfixadmin.tgz
