SpamAssassin past een uitgebreide benadering toe bij het nemen van beslissingen over blokkering: een bericht ondergaat verschillende controles (contextuele analyse, zwarte en witte lijsten DNSBL, leerbare Bayesiaanse classifiers, controle op handtekeningen, authenticatie van de afzender via SPF en DKIM, enzovoort). Na evaluatie van de berichten met verschillende methoden, wordt er een bepaalde gewichtsfactor opgebouwd. Als de berekende factor een bepaalde drempel overschrijdt, wordt het bericht geblokkeerd of als spam gemarkeerd. Er zijn middelen voor automatische updates van de filterregels beschikbaar. Het pakket kan zowel op clientsystemen als op serversystemen worden gebruikt. De code van SpamAssassin is geschreven in Perl en wordt verspreid onder de Apache-licentie.      <\/p>\n<p>In deze nieuwe versie is een kwetsbaarheid (CVE-2020-1946) verholpen, die een aanvaller in staat stelt systeembestellingen uit te voeren bij <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/nl\/server\/dts-dronten\/\"   title=\"de server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2614\">de server<\/a> het installeren van ongeteste blokkeringregels van externe bronnen.  <\/p>\n<p>Onder de veranderingen die niet met beveiliging te maken hebben, wordt de verbetering van de werking van de plugins OLEVBMacro en AskDNS genoemd, verbetering van het proces van datamatching in de headers Received en EnvelopeFrom, correcties in het SQL-schema userpref, verbetering van de code voor controles in rbl en hashbl, en een oplossing voor problemen met de TxRep-tags.     <\/p>\n<p>Er wordt opgemerkt dat de ontwikkeling van de serie 3.4.x is stopgezet en er geen wijzigingen meer in deze tak zullen worden aangebracht. Alleen voor correcties van kwetsbaarheden zal een release 3.4.6 worden gecre\u00eberd indien nodig. Alle ontwikkelaarsactiviteit is gericht op de ontwikkeling van de tak 4.0, waarin een volledige ingebouwde verwerking van UTF-8 zal worden ge\u00efmplementeerd.<br \/>\n<br \/>Bron: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=54826\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0414\u043e\u0441\u0442\u0443\u043f\u0435\u043d \u0440\u0435\u043b\u0438\u0437 \u043f\u043b\u0430\u0442\u0444\u043e\u0440\u043c\u044b \u0434\u043b\u044f \u0444\u0438\u043b\u044c\u0442\u0440\u0430\u0446\u0438\u0438 \u0441\u043f\u0430\u043c\u0430 &#8212; SpamAssassin 3.4.5. \u0412 SpamAssassin \u0440\u0435\u0430\u043b\u0438\u0437\u043e\u0432\u0430\u043d \u043a\u043e\u043c\u043f\u043b\u0435\u043a\u0441\u043d\u044b\u0439 \u043f\u043e\u0434\u0445\u043e\u0434 \u0432 \u043f\u0440\u0438\u043d\u044f\u0442\u0438\u0438 \u0440\u0435\u0448\u0435\u043d\u0438\u044f \u043e \u0431\u043b\u043e\u043a\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u0438: \u0441\u043e\u043e\u0431\u0449\u0435\u043d\u0438\u0435 \u043f\u043e\u0434\u0432\u0435\u0440\u0433\u0430\u0435\u0442\u0441\u044f \u0440\u044f\u0434\u0443 \u043f\u0440\u043e\u0432\u0435\u0440\u043e\u043a (\u043a\u043e\u043d\u0442\u0435\u043a\u0441\u0442\u043d\u044b\u0439 \u0430\u043d\u0430\u043b\u0438\u0437, \u0447\u0451\u0440\u043d\u044b\u0435 \u0438 \u0431\u0435\u043b\u044b\u0435 \u0441\u043f\u0438\u0441\u043a\u0438 DNSBL, \u043e\u0431\u0443\u0447\u0430\u0435\u043c\u044b\u0435 \u0431\u0430\u0439\u0435\u0441\u043e\u0432\u0441\u043a\u0438\u0435 \u043a\u043b\u0430\u0441\u0441\u0438\u0444\u0438\u043a\u0430\u0442\u043e\u0440\u044b, \u043f\u0440\u043e\u0432\u0435\u0440\u043a\u0430 \u043f\u043e \u0441\u0438\u0433\u043d\u0430\u0442\u0443\u0440\u0430\u043c, \u0430\u0443\u0442\u0435\u043d\u0442\u0438\u0444\u0438\u043a\u0430\u0446\u0438\u044f \u043e\u0442\u043f\u0440\u0430\u0432\u0438\u0442\u0435\u043b\u044f \u043f\u043e SPF \u0438 DKIM \u0438 \u0442.\u043f.). \u041f\u043e\u0441\u043b\u0435 \u043e\u0446\u0435\u043d\u043a\u0438 \u0441\u043e\u043e\u0431\u0449\u0435\u043d\u0438\u044f \u0440\u0430\u0437\u043d\u044b\u043c\u0438 \u043c\u0435\u0442\u043e\u0434\u0430\u043c\u0438, \u043d\u0430\u043a\u0430\u043f\u043b\u0438\u0432\u0430\u0435\u0442\u0441\u044f \u043e\u043f\u0440\u0435\u0434\u0435\u043b\u0435\u043d\u043d\u044b\u0439 \u0432\u0435\u0441\u043e\u0432\u043e\u0439 \u043a\u043e\u044d\u0444\u0444\u0438\u0446\u0438\u0435\u043d\u0442. \u0415\u0441\u043b\u0438 \u0432\u044b\u0447\u0438\u0441\u043b\u0435\u043d\u043d\u044b\u0439 [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-99572","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.3 -
