-d domain_name

Specifies domain to check for deleted attribute, and, if set, purges the mailboxes in that domain. If -d is not specified, then all domains on this mail host are checked for the deleted attribute and all mailboxes in the deleted domains are purged. If the domain spans more than one mail host, then you need to run this command on each host. (This command uses the mailhost attribute to determine where to purge.)

-g grace_period

Specifies the number of days that a domain or user must be marked as deleted before this command is run.
