I need some advise/recommendations on an email retention solution. We run GW2012 and I would like to implement email archiving/retention. Currently the edict from management is that no employee can empty their trash. AS you can imagine the trash bins are getting very large.

So I am looking for a solution. I would love it to be open source (or at least inexpensive), easy to use, and of course work well with GW.

Thanks, Chris.
