What privacy and data retention concerns should I consider with a DMARC analyzer?

ByBrad Slavin

You should consider that a DMARC analyzer processes personal and sensitive data (IP addresses, domains, sender/recipient identifiers, message headers, and sometimes message samples), so you must define per‑type retention limits, apply anonymization/pseudonymization, choose a hosting model with appropriate control, enforce encryption/RBAC/audit logging, comply with GDPR/CCPA and sector rules (including cross‑border transfers and data subject rights),…

What are the best practices to follow when generating a DMARC record for a high-volume mailer?

ByBrad Slavin

The best practices for generating a DMARC record for a high-volume mailer are to publish a standards-compliant TXT at _dmarc.yourdomain with v=DMARC1; p=none (then ramp to quarantine and reject via pct), use relaxed alignment initially (aspf=r; adkim=r), set rua to a monitored mailbox or aggregator, be conservative with ruf (fo=1 or fo=d:s only if you…

What Is Baiting in Cybersecurity? Techniques, Real Examples, and Protection Strategies

ByBrad Slavin

Cybercriminals constantly develop new ways to exploit human behavior. While many organizations focus heavily on technical defenses like firewalls, endpoint protection, and encryption, attackers frequently target the weakest link in cybersecurity: people. One common social engineering tactic used by attackers is baiting. This technique relies on curiosity, temptation, and human psychology to trick victims into…

How can I check whether my emails meet DMARC alignment requirements?

How can I check whether my emails meet DMARC alignment requirements?

ByBrad Slavin

You can check whether your emails meet DMARC alignment by reading the message’s Authentication-Results headers to confirm that either SPF or DKIM passed in alignment with the visible From domain, validating your SPF/DKIM/DMARC DNS records with tools (dig, opendkim, DMARC analyzers), and continuously reviewing DMARC aggregate/forensic reports—ideally via DMARCReport—toverify alignment across all sources. Email authentication…

Every website you visit relies on a behind-the-scenes system that connects human-friendly domain names to machine-readable IP addresses. Without this system, accessing websites would require memorizing strings of numbers instead of simple URLs. At DMARCReport, we believe that understanding DNS fundamentals is essential not only for website functionality but also for email authentication, deliverability, and…
