3.10.3.1 Keeping Quotas in DBM Database

To use the DBM quota database, your copy of mailutils must be compiled with DBM support (one of `--with-gdbm', `--with-db2', `--with-ndbm', `--with-dbm' options to configure). Examine the of mail.local --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 explicitely listed in the database.

Value

The 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 limitation 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 database, specify its full name using `-q' or `--quota-db' in the invocation of mail.local. For example, in sendmail .mc file:

define(`LOCAL_MAILER_PATH', `/usr/local/libexec/mail.local') define(`LOCAL_MAILER_ARGS', `mail -q /etc/mail/quota.db $u')
