This reputation is the measure of trust that Internet Service Providers (ISPs), spam filters, and receiving mail servers place in the sender, and it directly influences whether messages are accepted, delivered to inboxes,…

Email security gateways are essential components in the modern cybersecurity landscape, acting as the first line of defense against threats such as spam, phishing, malware, and advanced persistent threats delivered via email. These gateways analyze, filter, and often quarantine messages before they reach the recipient’s mailbox, ensuring that only clean and legitimate content is allowed…

In the design of a robust and scalable email infrastructure, subdomains play a vital role by enabling fine-grained control over how email services are organized, managed, and secured. Subdomains are extensions of a primary domain that create distinct namespaces within a larger DNS structure. For instance, in the domain example.com, a subdomain such as mail.example.com…
