Samtidig er det blevet annonceret, at st\u00f8tten til Postfix 3.7, der blev udgivet i begyndelsen af 2022, er oph\u00f8rt. Projektets kode er skrevet i C og distribueres under EPL 2.0 (Eclipse Public License) og IPL 1.0 (IBM Public License).    <\/p>\n<p>Postfix er et af de sj\u00e6ldne projekter, der samtidig kombinerer h\u00f8j sikkerhed, p\u00e5lidelighed og ydeevne, hvilket er opn\u00e5et gennem en flerprocesserarkitektur, der isolerer individuelle h\u00e5ndterere, samt en streng politik for kodeformatering og audit af patches. For at beskytte mod fejl ved hukommelsesoperationer bruger projektet sikre varianter af funktioner til allokering og frigivelse af hukommelse, samt et s\u00e6t abstrakte wrapper-funktioner til h\u00e5ndtering af buffere (der kontrolleres for bufferoverl\u00f8b og adgang til frigivet hukommelse), filoperationer, outputformattering, buffered input\/output, samt strengmanipulationer (herunder muligheder for arbejde med strenge af vilk\u00e5rlig st\u00f8rrelse og automatisk resizing af strenge).      <\/p>\n<p> I henhold til den afsluttende automatiserede unders\u00f8gelse af omkring 500.000 mail <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/\" title=\"servere\" data-wpil-keyword-link=\"linked\">servere<\/a> (efter juli 2025 er offentligg\u00f8relsen af rapporter oph\u00f8rt), Postfix anvendes p\u00e5 37,88% (for et \u00e5r siden 36,81%) af mailserverne, mens Exim udg\u00f8r 55,59% (for et \u00e5r siden 56,61%), Sendmail 3,55% (3,60%), MailEnable 1,81% (1,82%), MDaemon 0,40% (0,40%), Microsoft Exchange 0,20% (0,19%), OpenSMTPD 0,12% (0,09%).          <\/p>\n<p>Hovednyhederne:  <\/p>\n<ul>\n<li class=\"l\"> Der er udf\u00f8rt arbejde for at forenkle migrationen fra hash: og btree: s\u00f8getabeller til lmdb: eller cdb: i forbindelse med oph\u00f8ret af leveringen af BerkeleyDB-biblioteker i nogle Linux-distributioner. For at opretholde kompatibiliteten med Mailman-v\u00e6rkt\u00f8jet, der k\u00f8rer kommandoen postmap hash:\/path\/to\/file ved tilf\u00f8jelse eller fjernelse af mailinglister, er der tilf\u00f8jet st\u00f8tte til automatisk omdirigering af s\u00e5danne kommandoer til varianter med underst\u00f8ttede DB-typer i Postfix.\n<li class=\"l\"> Standard er der aktiveret forbindelser til SMTP-servere ved hj\u00e6lp af TLS-kryptering. I SMTP-klientindstillingerne er smtp_tls_security_level sat til 'may', hvis Postfix er bygget med TLS-underst\u00f8ttelse. V\u00e6rdien 'may' tillader brug af TLS for servere, der underst\u00f8tter kryptering, men tillader ogs\u00e5 tilbagevenden til ukrypteret dataoverf\u00f8rsel, hvis serveren ikke underst\u00f8tter TLS.\n<li class=\"l\"> I ESMTP er der implementeret st\u00f8tte til udvidelsen 'REQUIRETLS' (RFC 8689), som tillader afsenderen at anmode om garanteret TLS-kryptering i hele leveringsvejen for meddelelsen. I denne tilstand skal enhver SMTP- og LMTP-server, der deltager i omdirigeringen af brevet, underst\u00f8tte REQUIRETLS og streng autentificering via DANE eller STS, samt bruge REQUIRETLS ved overf\u00f8rsel af meddelelsen gennem en k\u00e6de af andre servere.\n<li class=\"l\"> Der er sikret registrering i TLS-sikkerhedsniveau logs, dvs. hvis niveauet REQUIRETLS er anmodet til overf\u00f8rsel af meddelelsen, vil information om brugen af REQUIRETLS nu blive gemt i loggen.\n<li class=\"l\">  Tilh\u00e6ftet er parameteren smtp_tls_enforce_sts_mx_patterns, som inkluderer kompatibilitetsmodus mellem SMTP-klienten Postfix og MTA-STS (MTA Strict Transport Security) plugins, der kr\u00e6ver aktivering af TLSRPT-support for at omdirigere STS-attributter. N\u00e5r denne parameter er aktiveret, som standard, vil SMTP-klienten Postfix kun oprette forbindelse til MX-serveren, hvis dets navn svarer til skabelonen angivet i STS-politikkerne. Ellers vil den gamle adf\u00e6rd blive anvendt \u2014 muligheden for at oprette forbindelse til MX-servere baseret p\u00e5 MX-poster i DNS, hvis serverens certifikat overholder STS-politikkerne. MTA-STS mekanismen giver kunden, der opretter forbindelse via en usikker kommunikationskanal, mulighed for at blive informeret om muligheden og betingelserne for at etablere en sikker TLS-forbindelse. St\u00f8tte til parameteren er ogs\u00e5 tilf\u00f8jet i v\u00e6rkt\u00f8jerne postfix-tlspol og postfix-mta-sts-resolver.\n<li class=\"l\"> Der er tilf\u00f8jet underst\u00f8ttelse af kvante-modstandsdygtige krypteringsalgoritmer ved bygning med OpenSSL 3.5 og nyere versioner.\n<li class=\"l\"> 16 konfigurationsparametre er blevet klassificeret som for\u00e6ldede, og n\u00e5r de anvendes, vil der blive udskrevet en advarsel i loggen om deres fjernelse i en af de fremtidige udgivelser. Blandt de for\u00e6ldede parametre er der for eksempel inkluderet \u00abvirtual_maps\u00bb, \u00abfallback_relay\u00bb, \u00abpostscreen_whitelist_interfaces\u00bb og \u00absmtpd_client_connection_limit_exceptions\u00bb.\n<li class=\"l\"> Der er tilf\u00f8jet support til at udskrive data i JSON-format for kommandoerne: \u00abpostconf -j|-jM|-jF|-jP\u00bb, \u00abpostalias -jq|-js\u00bb, \u00abpostmap -jq|-js\u00bb og \u00abpostmulti -jl\u00bb.\n<li class=\"l\"> Fejlh\u00e5ndteringen i Milter-filtre er blevet forbedret, hvilket opst\u00e5r ved behandling af meddelelser modtaget gennem l\u00e6nge etablerede SMTP-forbindelser. V\u00e6rdien af parameteren #milter_default_action er \u00e6ndret fra \u00abtempfail\u00bb til \u00abshutdown\u00bb, hvilket indeb\u00e6rer lukning af forbindelsen til klienten.        <\/ul>\n<p>Kilde: <a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=64928\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041f\u043e\u0441\u043b\u0435 \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; 3.12.0. \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 3.7, \u0432\u044b\u043f\u0443\u0449\u0435\u043d\u043d\u043e\u0439 \u0432 \u043d\u0430\u0447\u0430\u043b\u0435 2022 \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).
