Mail-flow discovery
Document domains, inbound and outbound routes, gateways, connectors, aliases, shared addresses, applications, bulk senders and relay dependencies before changing delivery or DNS.

Where the work begins
Build the decision around the business requirement.
Modern email protection is broader than rejecting unsolicited bulk mail. It must address impersonation, malicious links and attachments, compromised senders, legitimate bulk services and business-critical messages that cannot simply disappear. Atmic helps organisations map mail flow, configure available filtering and authentication controls, design quarantine and reporting processes, and define what administrators and users should do when suspicious mail gets through.
Problems we help address
Clarity before configuration.
Users receive phishing, impersonation and malicious content despite basic filtering, but the organisation has little evidence about why messages were allowed or blocked.
SPF, DKIM and DMARC records are absent, incomplete or changed without an inventory of legitimate services that send mail for the domain.
Quarantine notifications and release permissions create either excessive help-desk work or an unsafe route for users to restore harmful messages.
Mail-routing connectors, relays, applications and marketing platforms have accumulated without clear owners or documented authentication.
User reporting, administrator investigation and escalation steps are inconsistent, so useful warning signals do not become timely action.
Scope and capabilities
What a well-scoped engagement can include.
Final scope depends on the environment, priorities, product entitlements and agreed responsibilities.
Spam, phishing and malware policy
Configure the available reputation, content, attachment, link, impersonation and malware controls according to risk. Tune actions for reject, quarantine, warning or delivery rather than applying one response to every signal.
Email authentication
Inventory authorised senders and plan SPF, DKIM signing and DMARC alignment. Introduce DMARC policy in measured stages using reporting to find legitimate sources before stronger enforcement.
Quarantine and exception workflows
Define who can review, release, allow or block messages; how high-risk detections are handled; how temporary exceptions expire; and which events require administrator review.
User reporting and awareness alignment
Provide a practical reporting route and short guidance for suspicious messages, credential requests and payment changes. User awareness supports controls but does not transfer responsibility from technical safeguards.
Monitoring and operational review
Establish message-trace, authentication-report, policy-hit and false-positive review practices, including named owners, retained evidence and escalation into the wider incident process.
Potential business benefits
Designed for usefulness after handover.
Email policy based on known domains, senders and business workflows.
Greater visibility into suspicious messages, false positives and sender-authentication gaps.
More controlled quarantine release and exception handling.
A safer path toward DMARC enforcement without overlooking legitimate senders.
Clear actions for users, help-desk staff, mail administrators and security responders.
Practical use cases
Strengthen Microsoft 365 or Google Workspace email
Review native controls, domains, connectors, privileged roles, quarantine, user reporting and authentication records; then tune policies using representative message data.
Introduce a secure email gateway
Map the current route, validate capacity and continuity, configure accepted domains and policies, pilot mail flow, change DNS deliberately and retain rollback and message-trace procedures.
Reduce domain impersonation
Inventory authorised senders, repair SPF and DKIM where applicable, collect DMARC reports and progress policy only after legitimate services and forwarding effects are understood.
Assessment and implementation
A controlled route from current state to usable outcome.
Each stage establishes evidence for the next decision. The sequence is adjusted to suit risk, dependencies and change windows.
Inventory mail and senders
Capture domains, platforms, DNS, routing, connectors, applications, bulk senders, current controls, administrator roles and recent mail issues.
Design layered policy
Agree detection actions, impersonation protection, attachment and link handling, authentication stages, quarantine roles and escalation criteria.
Configure and observe
Introduce settings in audit, monitoring or pilot modes where available, verify mail flow and collect evidence about legitimate and unwanted traffic.
Tune and enforce
Resolve false positives and authorised-sender gaps, strengthen controls in stages, test reporting and document time-bound exceptions.
Handover operations
Provide policy records, trace and release procedures, authentication ownership, review cadence and links to the organisation's incident workflow.
Typical deliverables
Artifacts your team can use.
- Mail-flow, domain and authorised-sender inventory.
- Filtering, phishing, malware and impersonation policy design.
- SPF, DKIM and staged DMARC implementation plan.
- Quarantine, release, reporting and exception workflow.
- Pilot and tuning record with validation checklist.
- Administrator runbook and concise user guidance.
Planning considerations
Dependencies to surface early.
- No email filter can identify every harmful message or avoid every false positive; response and review processes remain necessary.
- SPF has lookup and design constraints, DKIM depends on each sending service, and DMARC enforcement should follow authorised-sender discovery.
- Forwarding, mailing lists and third-party senders can affect authentication alignment and require careful analysis.
- DNS ownership, TTLs, vendor lead times and access to sending platforms can control the implementation schedule.
- Encrypted or password-protected content may limit inspection, and business handling rules are needed for legitimate exceptions.
- Continuous mailbox monitoring and incident response are not implied by product configuration.
Frequently asked questions
Useful questions before you begin.
Will SPF, DKIM and DMARC stop all phishing?
No. They help receiving systems evaluate whether mail using a domain is authorised and aligned, but attackers can use lookalike domains, compromised accounts or other channels. Filtering, identity protection, user reporting and incident response are still required.
Why not set DMARC to reject immediately?
If legitimate senders are missing or misconfigured, immediate enforcement can reject wanted mail. A staged process uses reports and controlled policy changes to identify authorised sources, establish DKIM or SPF alignment, and reduce disruption before stronger enforcement.
Should users be allowed to release quarantined mail?
It depends on the detection type and risk. Low-risk bulk classifications may allow self-service, while phishing, malware or high-confidence impersonation may require administrator review. The platform's available roles and audit trail should support the chosen workflow.
Do we still need user awareness training?
Yes, because some malicious messages will resemble legitimate business requests and some attacks use compromised trusted accounts. Training should be concise and paired with an easy reporting route, prompt investigation and technical controls.
Does the service include continuous threat monitoring?
Not unless separately agreed. The implementation can establish alerts, reports and procedures, but ongoing review, response times and 24-hour analyst coverage require defined staffing or a contracted monitoring service.
