implementing folder hashing

[Manuel Delgado]

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.

Regards
Manuel Delgado
