If set to a value of zero or higher, users have their INBOX folders created
upon a successful login event or upon *lmtpd(8)* message delivery if
*autocreate_post* is enabled, provided their INBOX did not yet already
exist.

The user's quota is set to the value if it is greater than zero, otherwise
the user has unlimited quota.

Note that quota has kibibyte granularity.  Values specified here will be
truncated to the nearest whole kibibyte.

For backward compatibility, if no unit is specified, kibibytes is assumed.
