Mail-in-a-Box with Quotas
|
||||
=========================
|
||||
|
||||
This is an experimental implementation of Main-in-a-box with quotas. Follow the directions below to install except
|
||||
clone from this repository instead of the official repository.
|
||||
|
||||
There is no support for quotas in control panel at the moment. To set quotas for a user you need to set the `quota`
|
||||
column for the user in the `users.sqlite` database. The `quota` column is text and allows for the `M` and `G` suffixes
|
||||
for megabytes and gigabytes respectively. No spaces should be used in the quota value (e.g. `2G` or `100M`).

# UNIX socket (quota-warning below).

# dict: Keep quota stored in dictionary (eg. SQL)
