Each mailbox is defined as a User in the Admin Panel. Here you can manage all of your Users: add new ones, remove or edit any user's settings, as well as login into the User's Control Panel to manage their preferences.
Before adding a new user please make sure you have a sufficient User quota (available mailboxes and quota), which can be checked in the top menu bar of your Admin Panel.
Choose the Domain where you want to add an account from the drop-down list.
Enter the Username to add (only the part before the @ sign).
Enter the Password. Note: Passwords must contain at least 8 characters, including upper/lowercase, numbers, and a symbol.
Enter the Name of the user to add, for your control (user´s full name, with spaces).
Enter the Quota for the user, in Gigabytes (GB). In order to assign 5GB, simply type 5. To specify 500 MB (Half of a gigabyte), specify 0.5.
Optional: you can click on More Options to define the User's Language, Timezone or Localization and Date format.
Click on the button Add User to finish.
If you receive the error that the User already exists, check if you already have an Alias or a Distribution List with the same name. The username must be unique on a domain level, which means you cannot have a mailbox and an Alias with the same name.
Select your domain from the Select Domain drop-down box.
Click on the pencil icon (edit) next to the User you wish to edit
You can update the:
Account type (change from Basic to Enhanced and vice versa)
Quota (increase or decrease)
Click on More Options to update the:
Disabled - set to Yes if you want to temporarily deactivate the mailbox, without deleting the emails.
Only local SMTP - enable this if you want to restrict the User to only send local emails (only to the same domain).
Click on Update User to save your changes.
Logging in as a user
Admins are able to log in as the User, making it possible to manage several aspects, such as autoresponder, forwarders, rules, black & whitelist on user level, track e-mails sent by account (in Track deliveries) and so on, which are only available on the user level. End users can login with their respective e-mail addresses directly to the User Panel.
