If a user sends an email to a group of ten people within the same mail domain and attaches a 500k file, does Groupwise replicate the attachment ten times? Does this add 5 Mb to the post office or does it replicate it once within the post office and allow those ten users to access it? Is one copy deleted as each user deletes this mail item from their mailbox? If it is only one copy, does it get deleted from the post office when the last person to have a pointer there deletes the related mail item? I am trying to have our users in general be more aware of how much crap they fill our network space with (half a dozen versions of a certain letter or spreadsheet that never get eliminated when the final good version is completed for example). I would like them to post the same attachment to an area of the network shared by those ten and send an email telling the others that it is available and where to get it. Am I saving space?
