Email Gateway
An email gateway is a software or hardware solution that acts as an intermediary for email traffic between internal networks and the internet, handling tasks like filtering, routing, and security. It processes inbound and outbound emails to enforce policies, block threats such as spam and malware, and ensure compliance with regulations. Common features include spam filtering, virus scanning, encryption, and data loss prevention.
Developers should learn about email gateways when building or maintaining systems that involve email communication, such as enterprise applications, customer support platforms, or marketing tools, to ensure secure and reliable email delivery. It is crucial for implementing email security, compliance with standards like GDPR or HIPAA, and optimizing email infrastructure in cloud or on-premises environments.
