Storage might be cheep, but backing it all up, can be a nightmare. As for a legal requirement, to keep messages, about "You have left your car lights on", or "can someone give me a lift tomorrow", I don't think there are too many. Lots of emails have a life time, weather it be a few days, or 50 years. I also get quotes for computer equipment, that after a year is of no use. Lets not mention system messages, that I for one don't want to keep indefinatly.
Having 1 time on the system for all emails, is very limiting, because of the fact that some emails need longer than others. But this could be used as the standard for all emails not already marked.
I don't want to bring up Outlook, but at least it is able to set an archive time on folders, and I always used these to archive system messages after 90 days to the bin.
I would like to see Zimbra set a new standard in email organisation. To many of us, just never tidy up after ourselfs.
