Advanced Security Measures

Postfix also includes several security features like access control per recipient, sender or client, an SPF plugin to verify email senders, content filtering, and DNS whitelist support. It's designed to handle multiple connections from clients at the same time while managing rate limits for each one.

You'll find support for IPv6, TLS (Transport Layer Security), SMTP (Simple Mail Transfer Protocol), LMTP (Local Mail Transfer Protocol), QMQP (Quick Mail Queueing Protocol), SASL (Simple Authentication and Security Layer), and ETRN (Extended SMTP).
