Explanation

A mail gateway is a specialized software that connects different email systems and transfers messages between them. Unlike generic gateways, mail gateways handle email-specific protocols (SMTP, POP, IMAP) and format conversions. Bridges connect network segments, while user agents are email clients (like Outlook or Gmail) used by individuals. Mail gateways ensure interoperability between heterogeneous email systems.
