The project's code is written in C and is distributed under the GPLv2+ license. According to an automated survey of around 500,000 mail servers, Exim holds a 56% share (down from 59.06% a year ago), while Postfix is used on 37.45% (previously 34.68%) of mail servers, Sendmail at 3.53% (3.42%), MailEnable at 1.84% (1.81%), MDaemon at 0.40% (0.37%), and Microsoft Exchange at 0.20% (0.17%).       <\/p>\n<p>  Key Changes:  <\/p>\n<ul>\n<li class=\"l\"> Support for the ESMTP command \u2018ATRN\u2019 (Authenticated TURN) has been added, which allows switching roles between server and client during message delivery. This command can be utilized to facilitate email delivery for systems with dynamic IP addresses or intermittent internet access. Such a system can connect to the SMTP server as a client, then use the ATRN command to take on the role of server for receiving accumulated messages. The command can only be used after successful authentication and with an allowed ACL (acl_smtp_atrn).\n<li class=\"l\"> Most Exim components can now be built as loadable modules. For example, the JSON and LDAP lookup engines, filters, authentication and routing drivers, PAM, RADIUS, Perl, SPF, DKIM, DMARC, and ARC components, as well as all types of transportation besides SMTP, can be structured as loadable modules.\n<li class=\"l\"> The ability to disable support for Exim filters and Sieve at the build stage has been implemented.\n<li class=\"l\"> Support for DNS SRV (Service Location Record) records has been added to determine the support of TLS (Transport Layer Security) by mail receivers. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-dusseldorf\/\"   title=\"servers\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3465\">servers<\/a> receivers.\n<li class=\"l\"> An experimental build option \u2018EXPERIMENTAL_SPF_PERL\u2019 has been introduced, which includes an alternative implementation of the SPF (Sender Policy Framework) authentication mechanism, using the Perl module Perl Mail::SPF instead of the libspf2 library, which has encountered maintenance issues.\n<li class=\"l\"> An experimental build option \u2018EXPERIMENTAL_NMH\u2019 has been added, which implements a lookup engine for verification. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/lir\/ipv4\/\"   title=\"(the key to connect to is specified, and iroh finds the associated host and establishes an encrypted connection using the QUIC protocol).

You can run your own relay or connect to public relays supported by the community.<\/a> in the NMH (Net-Masked Hero) store.\n<li class=\"l\"> The configuration file has been updated with the setting \u2018tls_early_banner_hosts\u2019 to define the hosts to which the \u2018TLS Early Data\u2019 (0-RTT) mechanism will apply for sending the SMTP banner before the TLS connection negotiation is complete.\n<li class=\"l\"> The option \u2018sieve_inbox\u2019 has been added to specify the name of the mailbox file where messages redirected using the \u2018redirect_router\u2019 setting will be saved in Sieve filters.\n<li class=\"l\"> A variable \u2018connection_id\u2019 has been added, containing the identifier of the accepted connection. This variable can be used when configuring the log output format.\n<li class=\"l\"> The events smtp:fail:protocol and smtp:fail:syntax have been implemented, allowing tracking of errors related to the protocol and syntax of SMTP commands.\n<li class=\"l\"> The transport \u2018socks_proxy\u2019 can now accept an empty string value, which will be interpreted as no proxying.\n<li class=\"l\"> Variables $dmarc_alignment_spf and $dmarc_alignment_dkim have been added, reflecting the results of SPF and DKIM checks.\n<li class=\"l\"> Support for IPv6 connections when accessing MySQL and PostgreSQL databases has been added.\n<li class=\"l\"> The sender address (envelope-from) specified in the transport parameters has been allowed for direct deliveries (cutthrough deliveries) and recipient existence checks.\n<li class=\"l\"> The ability to use variables and expressions for the dynamic formation of the options &#171;hosts_randomize&#187; in the &#171;manualroute&#187; router and &#171;smtp&#187; transport has been added. Similarly, support has been added for the dynamic formation of the &#171;fallback_hosts&#187; options in all routers and the &#171;smtp&#187; transport.\n<li class=\"l\"> The &#171;log_ports&#187; option has been added to the configuration file for filtering the port numbers reflected in the logs. For example, by specifying &#171;log_ports = !25 : !587&#187;, the log will display entries for outgoing_port and incoming_interface that are not related to ports 25 and 587.\n<li class=\"l\"> The ability to reflect in the delivery log information about commands and responses transmitted during the establishment of the SMTP connection, as well as details about the use of TLS during the connection (label &#171;tls_on_connect&#187;), has been added.\n<li class=\"l\"> The &#171;no_wr&#187; option has been added to disable writing results of lookup operations to the cache.\n<li class=\"l\"> A command line option &#171;-dS&#187; has been added to output debug information during the stage before parsing the configuration file.\n<li class=\"l\"> Tags &#171;H=&#187; and &#171;U=&#187; reflecting the host and username have been added to the log for messages related to authentication failures.      <\/ul>\n<p>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=64130\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0440\u0435\u043b\u0438\u0437 \u043f\u043e\u0447\u0442\u043e\u0432\u043e\u0433\u043e \u0441\u0435\u0440\u0432\u0435\u0440\u0430 Exim 4.99, \u0432 \u043a\u043e\u0442\u043e\u0440\u044b\u0439 \u0432\u043d\u0435\u0441\u0435\u043d\u044b \u043d\u0430\u043a\u043e\u043f\u0438\u0432\u0448\u0438\u0435\u0441\u044f \u0438\u0441\u043f\u0440\u0430\u0432\u043b\u0435\u043d\u0438\u044f \u0438 \u0434\u043e\u0431\u0430\u0432\u043b\u0435\u043d\u044b \u043d\u043e\u0432\u044b\u0435 \u0432\u043e\u0437\u043c\u043e\u0436\u043d\u043e\u0441\u0442\u0438. \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\u0435\u0439 GPLv2+. \u0412 \u0441\u043e\u043e\u0442\u0432\u0435\u0442\u0441\u0442\u0432\u0438\u0438 \u0441 \u0430\u0432\u0442\u043e\u043c\u0430\u0442\u0438\u0437\u0438\u0440\u043e\u0432\u0430\u043d\u043d\u044b\u043c \u043e\u043f\u0440\u043e\u0441\u043e\u043c \u043e\u043a\u043e\u043b\u043e 500 \u0442\u044b\u0441\u044f\u0447 \u043f\u043e\u0447\u0442\u043e\u0432\u044b\u0445 \u0441\u0435\u0440\u0432\u0435\u0440\u043e\u0432, \u0434\u043e\u043b\u044f Exim \u0441\u043e\u0441\u0442\u0430\u0432\u043b\u044f\u0435\u0442 56% (\u0433\u043e\u0434 \u043d\u0430\u0437\u0430\u0434 59.06%), Postfix \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u0443\u0435\u0442\u0441\u044f \u043d\u0430 37.45% (34.68%) \u043f\u043e\u0447\u0442\u043e\u0432\u044b\u0445 \u0441\u0435\u0440\u0432\u0435\u0440\u043e\u0432, Sendmail &#8212;
