Postfix is an attempt to provide an alternative to the widely-used Sendmail program. Postfix attempts to be fast, easy to administer, and hopefully secure, while at the same time being sendmail compatible enough to not upset your users.

Postfix no longer automatically appends the system default CA certificates. When pipe-to-command delivery fails with a signal, mail is now correctly deferred, instead of being returned to sender. Poor `smtpd_proxy_filter` TCP performance over loopback (127.0.0.1) connections was fixed by adapting the output buffer size to the MTU. The SMTP server no longer applies the `reject_rhsbl_helo` feature to non-domain forms such as network addresses. The Postfix SMTP server failed to deliver a "421" response and hang up the connection after Milter error.
