Prepared by

A default mailbox exists for the domain, but it cannot be used until an identity is created. Do not attempt to enable DKIM yet.

Prerequisites

  • SSL is configured and validated for the account domain
  • DNS and nameserver prerequisites are complete
  • Redis and supporting services are confirmed running

Create the Admin Mailbox Identity using Roundcube

  • From DirectAdmin Control Panel | USER
  • Go to <Extra Features> | <Webmail: Roundcube>.
    • Use same admin credentials as DirectAdmin.
    • From left frame, tap on “Settings”.
    • Click on “Identities”.
    • Observe that the default admin email address identity pre-exists for the entire server as admin@localhost. Be sure to leave it alone.
    • Now, add this domain’s unique admin email identity.
      • Tap <+> Create icon from top and make changes as follows:
        • Display Name: ( Admin)
          • Examples: PrimaryVPS Admin, Linxent Admin, BaygentsOrg Admin
        • Email: (admin@)
          • Important: Do NOT change the name “admin” for this initial mailbox. Many systems rely on the existence of a default “admin” mailbox.
        • Organization: (empty)
        • Reply-To: (empty)(leave empty so it won’t overwrite other domains reply-to email address)
        • Bcc: (empty)
        • Set default: disabled (enabled is only for default initial one for the account domain >> admin@localhost)
        • Signature: (empty)
        • Click <Save>
      • Optionally, you can Create other users at this time; however, unless it’s not urgent, it’s recommended to continue with remaining steps and add more users later when time permits.
      • Close Mail session.
