Hi everyone, I want to ask if any of you has done a migration from a single storage to multiple back-end storages and what is the best strategy for folder hashing that you use. Using something like %H or %M how do you predict where the mail will end up in order to move the existing folders ? Thank you ! -- Best regards, Adrian Minta
Hi Adrian, It depends much on your site configuration. In our case, we have several mount points and we distribute our user mailboxes using username hash (%N)[1] and limit this hash to the number of mount points. We preferred %N over %H because the distribution of users was much better. Ex. xstore%2.3Nn turns to xstore00, xstore01 and xstore03.

Thank you for your reply. One questionthough, if you add a mount point how do you know what user to move ?
