recently i had to set up a Distribution List for my Zimbra Server for an announcemnt list. The Idea was to be able to inform all our users about our maintenance plans etc. When i wanted to send another email, i already got annoyed updating this list manually and i really did not want to do this every single time again.
So i decided to write a little zmprov script to update the list and after years of beneft from the Zimbra Community i thought it would be nice to give something back. I placed it on github and here is my first draft and dirty hack of zannounce: https://github.com/jafeha/zimbra_scripts
I know there might be better way to do this or smarter code to write, but it works for me for the moment and i hope someone else finds it useful.
Tested on Zimbra FOSS 8.0.6
