3.12.4.1 Keeping Quotas in DBM File

To use DBM quota database, GNU Mailutils must be compiled with one of the following command line options: --with-gdbm, --with-berkeley-db, --with-ndbm, --with-tokyocabinet, or --with-kyotocabinet. Examine the output of mda --show-config-options, if not sure.

The quota database should have the following structure:

Key

Key represents the user name. Special key ‘DEFAULT’ means default quota value, i.e. the one to be used if the user is not explicitly listed in the database.

Value

Mailbox quota for this user. If it is a number, it represents the maximum mailbox size in bytes. A number may optionally be followed by ‘kb’ or ‘mb’, meaning kilobytes and megabytes, respectively.

A special value ‘NONE’ means no mailbox size limit for this user.

Here is an example of a quota database in text form:

# Default quota value:
DEFAULT         5mb

# Following users have unlimited mailbox size
root            NONE
smith           NONE

# Rest of users
plog            26214400
karin           10mB

To use the DBM quota database, specify its absolute name using the database configuration statement in the quota section, e.g.:

quota {
  database /etc/mail/quota.db;
}
