Dada Mail manages subscriber lists and campaign distribution, so the core risk is unauthorized list access and SMTP abuse. Harden admin auth, list privacy, and mail relay restrictions.
¶ 1) Harden administrator and list-owner access
- Restrict global admin accounts to dedicated operators.
- Enforce strong passwords and session timeout policies.
- Disable public list-management endpoints where not required.
- Audit list-owner privileges and remove stale accounts.
¶ 2) Protect subscriber data and campaign operations
- Keep subscriber exports restricted to privileged roles only.
- Encrypt backups containing subscriber addresses and campaign metadata.
- Limit upload/import operations to trusted users.
- Define retention policy for old campaign logs and bounce data.
¶ 3) Prevent SMTP and relay abuse
- Use authenticated SMTP with TLS only.
- Restrict envelope sender domains and SPF/DKIM alignment.
- Apply sending limits and queue monitoring to detect abuse.
- Monitor bounce and complaint rates for account compromise signals.
