3.11.4.1 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 maidag --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 valid quota database

     # 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 quota-db configuration statement, e.g.:

     quota-db /etc/mail/quota.db;
