Under the "Advanced" tab of the default class of service configuration, there is this option:

"E-mail message lifetime:"

My question is, what does this do? I thought it was going to be a way of setting an email retention policy -- but this does not seem to be the case. Zimbra retains all messages in users' folders, regardless of what this is set to.

We are an organization that needs to setup email retention policies. The idea is that if we ever get sued, we don't have to go through years and years of emails. If we set our retention policy to say 6 months, we will only need to dig through that much smaller amount of email. Any ideas?

Thanks,
Ryan
