If set to a value of zero or higher, users who have their INBOX folders
created upon a successful login event (see *autocreate_quota*), or upon
*lmtpd(8)* message delivery if *autocreate_post* is enabled, receive the
message quota configured in this option.

The default of -1 disables assigning message quota.

For consistency with *autocreate_quota*, a value of zero is treated as
unlimited message quota, rather than a message quota of zero.
