Mailbox activation checklist

01 · DOMAIN

Confirm control

• Confirm authorised administrative access to arbaminchwater.com.
• Record the current DNS and mail provider before changing anything.
• Schedule changes to avoid disrupting any existing mail service.

02 · HOST

Select the mailbox service

• Choose a service that supports 15 individual mailboxes, MFA, audit logs, backups, and administrator recovery.
• Confirm storage, mobile access, retention, and support requirements.
• Do not use forwarding-only email routing as a replacement for staff inboxes.

03 · ACCOUNTS

Create and verify

• Import the supplied CSV or create the 15 addresses exactly as approved.
• Verify the two name/address spelling differences before activation.
• Use temporary passwords and require a change at first sign-in.

04 · SECURITY

Protect the domain

• Publish provider-approved SPF and DKIM records.
• Start DMARC in monitoring mode, review reports, then strengthen the policy.
• Require multi-factor authentication for administrators and staff.

05 · TEST

Prove delivery

• Test sending and receiving inside and outside the organisation.
• Check spam placement, replies, mobile sign-in, and password recovery.
• Test each mailbox with real addresses controlled by the enterprise.

06 · OPERATE

Run it responsibly

• Document joiner, mover, and leaver procedures.
• Review account access and mail security reports regularly.
• Keep credentials, recovery codes, and backups outside this website repository.
