I am not saying that all email should be deleted, but as the KB points out, where high numbers come from is when 1 message is sent to hundreds of different mailboxes. I would argue that when that happens, rarely should those messages be kept by all "hundreds" of recipients for a long period of time. It probably applies to a small subset of those who received it, or it is the typical "Don't forget the company picnic this weekend" stuff, that everyone gets and not nearly enough people get rid of. Rarely will an email that will save your company's bacon be received by over 100 recipients at one time. Not saying it doesn't happen, just that it would be rare. That is why I would say that on a mature server a number in the 100 range or higher shows a lack of good email hygiene on the server in question. TVK

This idea that one shouldn't use an email system to store email always seemed kind of strange to me. Keep in mind that I'm quite religious about filing mail. My inbox is usually empty, and my "Inbox/todo" folder typically has < 20 messages in it. But I've got hundreds of folders of archived mail, all carefully sorted by project, application, category, etc. It totals around 500 MB for the four years I've been at this company. No idea how many messages. It's all in Public Folders, too, so that the rest of the IT department (i.e., one other guy :-) ) can find stuff if needed. > Unless of course you are in the legal industry or something > similar where all correspondence must be kept forever. Many people, including myself and many of my cow-orkers, are in the habit of retaining business correspondence "forever", just on general principles. I know we've frequently encountered situations where a customer will come back to us five years later alleging something, and it's only been the saved mail which has saved our butts. -- Ben ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~ ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
