Properly functioning email infrastructure is dependent on accurate and well-maintained DNS records, particularly those governing mail routing and authentication such as MX, SPF, DKIM, and DMARC. When email delivery problems arise or proactive testing is required to ensure optimal configuration, DNS lookup tools play an essential role. These tools allow administrators to query public DNS…

Setting up SPF records correctly is a foundational task in securing your domain against email spoofing and improving deliverability. Sender Policy Framework, or SPF, is a DNS-based email authentication mechanism that allows domain owners to specify which mail servers are permitted to send email on behalf of their domain. When a receiving mail server gets…

Data sovereignty refers to the concept that digital information is subject to the laws and governance structures within the nation where it is stored or processed. As email is one of the most ubiquitous forms of digital communication and often carries sensitive or regulated data, ensuring compliance with data sovereignty requirements is a growing concern…

Domain ownership disputes can be highly disruptive, particularly when they affect critical services such as email communication. Email systems rely heavily on DNS, and especially MX records, to function correctly. When the control of a domain is contested or changes hands under unclear or contentious circumstances, email delivery may be interrupted, misrouted, or exploited. These…

Ensuring HIPAA compliance in email communication requires a careful alignment between regulatory obligations and the technical infrastructure underpinning email systems, including Domain Name System (DNS) configurations and Mail Exchange (MX) records. The Health Insurance Portability and Accountability Act (HIPAA) mandates strict protections for electronic protected health information (ePHI), and any covered entity or business associate…

The Domain Name System is one of the most foundational components of internet infrastructure, enabling the translation of human-readable domain names into IP addresses that computers use to communicate. For email systems in particular, DNS is vital, as it houses MX (Mail Exchange) records that define where incoming email should be routed. Alongside MX records,…

The QUIC protocol, originally developed by Google and later standardized by the IETF, represents a major shift in how data is transmitted over the internet. Designed as a modern alternative to the traditional TCP+TLS stack, QUIC operates over UDP and integrates features such as multiplexing, encryption, and connection migration directly into the protocol itself. Its…

As the internet continues to expand and the number of connected devices grows exponentially, IPv6 adoption has become a necessity. Unlike its predecessor IPv4, which offers approximately 4.3 billion unique addresses, IPv6 supports a vastly larger address space—over 340 undecillion addresses—ensuring continued scalability of internet infrastructure. Email systems, like all internet services, must adapt to…

BIMI, or Brand Indicators for Message Identification, represents a significant advancement in both email authentication and visual brand representation within the inbox. This emerging standard allows organizations to display their official brand logos alongside authenticated email messages in supporting mail clients, offering a visually trusted indicator to recipients. At its core, BIMI is a DNS-based…

Email loops are a disruptive and potentially dangerous condition in which messages are continuously forwarded or bounced between two or more servers, often consuming system resources, generating large volumes of unnecessary email traffic, and in severe cases, overwhelming servers or triggering spam detection systems. These loops usually arise due to misconfigurations in mail routing, automatic…
