DKIM, SPF, DMARC Configuration
Protect Your Domain Against Email Fraud
By properly configuring your SPF, DKIM and DMARC records, we prevent spoofed email sending, reduce the risk of emails landing in spam folders and protect your corporate reputation.
We bring your email authentication in line with industry standards
We build an integrated email security architecture that goes beyond adding a single DNS record, covering all your sending sources, bulk email services and third-party applications.
SPF Record Design
We configure SPF records that clearly define which servers can send email on behalf of your domain, ensuring compatibility with M365, Google, cPanel and your bulk email services.
DKIM Key Management
We generate DKIM keys that cryptographically sign your emails, configure them correctly in DNS and prevent conflicts in environments using multiple services.
DMARC Policy Design
Instead of immediately switching your DMARC policy to “reject,” we increase your security level gradually through monitoring and controlled enforcement without unnecessary risk.
DMARC Reporting & Analysis
We set up systems that collect DMARC RUA and RUF reports, make it visible which IPs are attempting to send emails on your behalf and provide actionable recommendations based on the reports.
Multi-Service & Application Integration
We design an email authentication architecture that takes into account your M365, Google Workspace, ERP, CRM, helpdesk and bulk email platforms.
Continuous Monitoring & Optimization
We help you keep your SPF, DKIM and DMARC records up to date as IP addresses change, new services are introduced and bulk email campaigns are launched.
We implement DKIM, SPF and DMARC step by step
We analyze your domain, email services and existing DNS records and implement a gradual migration plan without taking unnecessary risks.
Current State Analysis
We identify the SPF, DKIM and DMARC status of your domain, along with the services and IPs in use.
Architecture & Record Design
We create a domain-specific design for your SPF structure, DKIM keys and DMARC policy.
DNS Implementation & Testing
We add the DNS records, validate them with testing tools and monitor their behavior on a pilot group.
DMARC Monitoring Mode
We initially use p=none for monitoring only, collecting and analyzing DMARC reports.
Gradual Enforcement
We move to quarantine and then reject policies to reach a level that blocks spoofed emails.
Sustainable Management
We provide guidance to keep your records up to date as new applications and services are introduced.
Email security is more than just a DNS record
Simply saying “let’s add SPF and set DMARC to reject” is often not enough and, if configured incorrectly, can even disrupt your business email traffic. İnvekor builds a living, manageable and monitorable architecture with both IT infrastructure and email security in mind.
