Email Infrastructure
Email Infrastructure refers to the comprehensive system of hardware, software, protocols, and services that enable the sending, receiving, routing, storage, and management of email communications. It includes components like mail servers (SMTP, IMAP, POP3), DNS records (MX, SPF, DKIM, DMARC), email clients, and security measures to ensure reliable and secure email delivery. This infrastructure is critical for both personal communication and business operations, handling everything from transactional emails to marketing campaigns.
Developers should learn Email Infrastructure when building applications that involve email functionality, such as user registration, password resets, notifications, or marketing automation. Understanding this is essential for ensuring email deliverability, avoiding spam filters, and implementing security best practices like authentication and encryption. It's particularly important for roles in DevOps, backend development, or system administration where maintaining reliable email services is a key responsibility.
