Domain status is active in the normal state, users can log in and mail is delivered. When you change the status for a domain, in many cases you affect the status for accounts on the domain also.
Procedure
Go to Configure>Domains and select the domain.
In the gear icon, click Edit.
In the Navigation pane, select General Information.
In the Status drop down menu select the status.
Active. Active is the normal status for a domain. Accounts can be created and mail can be delivered. If an account has a different status setting, the account status overrides the domain status.
Closed. When a domain status is Closed, account logins are disabled and messages are bounced. A domain status of Closed overrides an individual account's status setting.
Locked. When a domain status is locked, users cannot log in to check their email but email is still delivered to the accounts. If an account's status setting is Maintenance or Closed, the account's status overrides the domain status setting. For example, mail for accounts in the Maintenance status is queued at the MTA, not delivered.
Maintenance. When the domain status is Maintenance, users cannot log in and their email is queued at the MTA. If an account's status is Closed, messages are not queued.
Suspended. When the domain status is Suspended, users cannot log in, their mail is queued at the MTA, and accounts and distribution lists cannot be created, deleted, or modified. If an account's status is Closed, the account's status mail is not queued at the MTA.
Click Save.
