At the same time, support for the Postfix 3.6 branch, released in early 2021, has been discontinued. The project's code is written in the C language and is distributed under the EPL 2.0 (Eclipse Public License) and IPL 1.0 (IBM Public License).    <\/p>\n<p>Postfix is one of the rare projects that combines high security, reliability, and performance, achieved through a multi-processing architecture that isolates individual handlers, along with a strict code formatting and patch auditing policy. To protect against memory errors, the project uses secure variants of functions for memory allocation and deallocation, as well as a set of abstract wrapper functions for working with buffers (which check for buffer overflows and access to freed memory), file operations, output formatting, buffered input\/output, and string manipulation (including capabilities for handling strings of arbitrary size and automatic resizing).      <\/p>\n<p> According to a February automated survey of around 550,000 mail servers, <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/\"   title=\"servers\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"1686\">servers<\/a>, Postfix is used on 37.64% (up from 36.81% a year ago) of mail servers, while Exim's share is 56.03% (down from 56.61%), Sendmail \u2014 3.39% (3.60%), MailEnable \u2014 1.80% (1.82%), MDaemon \u2014 0.39% (0.40%), Microsoft Exchange \u2014 0.19% (0.19%), OpenSMTPD \u2014 0.10% (0.09%).      <center><img decoding=\"async\" alt=\"The mail server Postfix 3.10.0 has been released.\" src=\"\/wp-content\/uploads\/2025\/02\/d0a8ec5a067a9d674e2b77db68d1a4f0.gif\" style=\"display:block;margin: 0 auto;\" \/><\/center>                  <\/p>\n<p>Key innovations:  <\/p>\n<ul>\n<li class=\"l\"> Support has been added for using TLS cryptographic algorithms that are resistant to brute force attacks on quantum computers. To use these algorithms, the branch of the OpenSSL library 3.5 must be used, which is still under development. No new syntax for TLS groups has been introduced in Postfix for selecting post-quantum algorithms; instead, the settings in OpenSSL, which will be used when configuring the parameters 'tls_eecdh_auto_curves' and 'tls_ffdhe_auto_groups' with empty values, have been relied upon.\n<li class=\"l\"> Support has been added for the message header 'TLS-Required: no' (RFC 8689), which allows delivery to be carried out even when the specified TLS security policy cannot be implemented. With this header present, the SMTP client operates in 'smtp_tls_security_level = may' mode, meaning it does not verify the certificate. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-los-angeles\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3888\">server<\/a>   It can revert to a plaintext data transfer connection. In the next significant version of Postfix, we aim to implement the SMTP extension REQUIRETLS.\n<li class=\"l\"> Support has been added for the TLS-RPT (Transport Layer Security Reporting) protocol, which allows tracking delivery failures that occur when a secure connection mandated by the use of DANE (DNS-based Authentication of Named Entities) or MTA-STS (MTA Strict Transport Security) extensions cannot be established. The owner of a mail domain defines the parameters for TLS-RPT in DNS, after which mail servers will send reports with information about successful and failed TLS connections to the MX servers servicing the domain. The implementation is based on the libtlsrpt library.\n<li class=\"l\"> A new setting 'smtpd_hide_client_session = yes' has been added, which disables the insertion of client session information when the SMTP server substitutes the 'Received:' header. An example of a trimmed header is 'Received: by mail.example.com (Postfix) id postfix-queue-id for ; Day, dd Mon yyyy hh:mm:ss tz-offset (zone)'.\n<li class=\"l\"> The ability for MIME encoding (RFC 2047) of names in generated Postfix headers 'From:', which include non-ASCII characters, has been added. The proposed encoding scheme allows for the omission of the SMTPUTF8 extension (RFC 6531), which is not supported by all applications. The result of MIME encoding appears as ''=?charset?Q?gibberish?=;'. A parameter 'full_name_encoding_charset' has been added to determine the original encoding of names, defaulting to utf8.\n<li class=\"l\"> The logic for handling failed connections has been modified when specifying either &#171;mysql:&#187; or &#171;pgsql:&#187; with only one server in the settings. Such a server is now treated as a load balancer, and in the event of a single failure, the request is immediately retried without a 60-second delay.\n<li class=\"l\"> In Milter, the logging of information regarding the reason for placing a message in quarantine has been implemented.\n<li class=\"l\"> The SMTP server now logs the queue identifier or the value &#171;NOQUEUE&#187; when connections time out, are terminated, or exceed the error limit. The cleanup process logs &#171;queueid: canceled&#187; for messages that have initiated but not completed the transaction.\n<li class=\"l\"> In the Dovecot SASL client, when logging &#171;Invalid authentication mechanism&#187; messages, the authentication mechanism that failed to be used is now specified. The SMTP server now displays the values of sasl_method, sasl_username, and sasl_sender when logging &#8216;reject&#8217; entries.\n<li class=\"l\"> Due to changes in the internal protocol used by the delivery agent, after updating Postfix, it is required to restart with the command &#171;postfix reload&#187; or with the commands &#171;postfix stop&#187; and &#171;postfix start&#187;. Otherwise, the log will show a warning &#171;unexpected attribute smtputf8 from xxx socket (expecting: sendopts)&#187;.      <\/ul>\n<p>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=62741\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041f\u043e\u0441\u043b\u0435 \u043f\u043e\u0447\u0442\u0438 \u0433\u043e\u0434\u0430 \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u043a\u0438 \u043e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0440\u0435\u043b\u0438\u0437 \u043d\u043e\u0432\u043e\u0439 \u0441\u0442\u0430\u0431\u0438\u043b\u044c\u043d\u043e\u0439 \u0432\u0435\u0442\u043a\u0438 \u043f\u043e\u0447\u0442\u043e\u0432\u043e\u0433\u043e \u0441\u0435\u0440\u0432\u0435\u0440\u0430 Postfix &#8212; 3.10.0. \u0412 \u0442\u043e \u0436\u0435 \u0432\u0440\u0435\u043c\u044f \u043e\u0431\u044a\u044f\u0432\u043b\u0435\u043d\u043e \u043e \u043f\u0440\u0435\u043a\u0440\u0430\u0449\u0435\u043d\u0438\u0438 \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u043a\u0438 \u0432\u0435\u0442\u043a\u0438 Postfix 3.6, \u0432\u044b\u043f\u0443\u0449\u0435\u043d\u043d\u043e\u0439 \u0432 \u043d\u0430\u0447\u0430\u043b\u0435 2021 \u0433\u043e\u0434\u0430. \u041a\u043e\u0434 \u043f\u0440\u043e\u0435\u043a\u0442\u0430 \u043d\u0430\u043f\u0438\u0441\u0430\u043d \u043d\u0430 \u044f\u0437\u044b\u043a\u0435 \u0421\u0438 \u0438 \u0440\u0430\u0441\u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u044f\u0435\u0442\u0441\u044f \u043f\u043e\u0434 \u043b\u0438\u0446\u0435\u043d\u0437\u0438\u044f\u043c\u0438 EPL 2.0 (Eclipse Public license) \u0438 IPL 1.0 (IBM Public License).
