We have quotas on our mailboxes and the useres get an infomail if the mailbox is getting full. This gives them time do delete mails they no longer need (or move them to archive). So the problem with mailflow you want to solve is not realy a problem for us. With this change its not any more possible to keep a mailbox and the archiv small. An other point is that useres who have already some folders in thier archive possibly are confused and cant find thier mail. If you copy the folder structure from the mailbox and the same strucure already existy in the archive - what is autoarchiving doing in that case (two time the same folder name)?
Please give us a possibility to disable autoarchiving!!!
