The Admin Control Panel is located at this link: https://cp.emailarray.com/admin.
This interface will let you manage your domains, users, aliases, lists, branding and domain wide preferences. Many settings overlap with User defined settings and in those cases, the User preferences will take over. For example, as an Administrator you can blacklist the domain "abcd.com" but if a user whitelists "joe@abcd.com", the whitelist will take priority.
Check the pages below in order to find out how to perform common Administration tasks.
What's my Admin username?
When you signed-up for a PolarisMail account, you chose a username & password for managing your account. This is the Administrator's Account (we call it an Admin) that you use to login to the Admin Control Panel.
