O Rspamd suporta praticamente todas as funcionalidades implementadas no SpamAssassin e possui v\u00e1rias caracter\u00edsticas que permitem filtrar e-mails em m\u00e9dia 10 vezes mais r\u00e1pido do que o SpamAssassin, al\u00e9m de garantir uma melhor qualidade de filtragem. O c\u00f3digo do sistema \u00e9 escrito em C e <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/rspamd\/rspamd\">\u00e9 distribu\u00eddo<\/a><\/noindex> est\u00e3o sob a licen\u00e7a Apache 2.0. <\/p>\n<p>O Rspamd \u00e9 constru\u00eddo com uma arquitetura orientada a eventos e foi projetado para ser utilizado em sistemas de alta carga, permitindo processar centenas de mensagens por segundo. As regras para identificar sinais de spam s\u00e3o altamente flex\u00edveis e podem, na sua forma mais simples, conter express\u00f5es regulares; em situa\u00e7\u00f5es mais complexas, podem ser escritas na linguagem Lua. A amplia\u00e7\u00e3o da funcionalidade e a adi\u00e7\u00e3o de novos tipos de verifica\u00e7\u00f5es s\u00e3o realizadas atrav\u00e9s de m\u00f3dulos, que podem ser desenvolvidos em C e Lua. Por exemplo, est\u00e3o dispon\u00edveis m\u00f3dulos para verificar o remetente usando SPF, confirma\u00e7\u00e3o do dom\u00ednio do remetente atrav\u00e9s do DKIM, e forma\u00e7\u00e3o de consultas em listas DNSBL. Para facilitar a configura\u00e7\u00e3o, cria\u00e7\u00e3o de regras e monitoramento de estat\u00edsticas, uma interface web administrativa \u00e9 fornecida. <\/p>\n<p>Principais novidades:<\/p>\n<ul>\n<li class=\"l\"> Foi feita a transi\u00e7\u00e3o para um novo esquema de numera\u00e7\u00e3o de vers\u00f5es. Como o primeiro n\u00famero da vers\u00e3o n\u00e3o mudava h\u00e1 v\u00e1rios anos, e o verdadeiro indicador da vers\u00e3o \u00e9 o segundo n\u00famero, decidiu-se, em vez do esquema &#171;x.y.z&#187;, usar o formato &#171;y.z&#187;;\n<li class=\"l\"> Para o ciclo de processamento de eventos, em vez de <noindex><a rel=\"nofollow\" href=\"https:\/\/libevent.org\/\">Libevent<\/a><\/noindex> a biblioteca <noindex><a rel=\"nofollow\" href=\"http:\/\/software.schmorp.de\/pkg\/libev.html\">libev<\/a><\/noindex>, livre de algumas limita\u00e7\u00f5es do libevent e permitindo obter um desempenho maior. O uso do<br \/>\nlibev tornou poss\u00edvel simplificar o c\u00f3digo, melhorar o tratamento de sinais e prazos, al\u00e9m de unificar o monitoramento de altera\u00e7\u00f5es de arquivos usando o mecanismo inotify (nem todas as vers\u00f5es do libevent fornecidas para as plataformas suportadas poderiam funcionar com inotify);<\/p>\n<li class=\"l\"> O suporte ao m\u00f3dulo de classifica\u00e7\u00e3o de mensagens, que utiliza a biblioteca de aprendizado profundo Torch, foi encerrado. A raz\u00e3o mencionada \u00e9 a complexidade excessiva do Torch e o alto custo de manuten\u00e7\u00e3o para mant\u00ea-lo atualizado. Como substituto para a classifica\u00e7\u00e3o utilizando m\u00e9todos de aprendizado de m\u00e1quina, foi proposto um m\u00f3dulo totalmente reescrito. <noindex><a rel=\"nofollow\" href=\"https:\/\/rspamd.com\/doc\/modules\/neural.html\">Neural<\/a><\/noindex>, no qual uma biblioteca \u00e9 utilizada para garantir o funcionamento da rede neural. <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/attractivechaos\/kann\">kann<\/a><\/noindex>, contendo apenas 4000 linhas de c\u00f3digo em C. Na nova implementa\u00e7\u00e3o, muitos problemas relacionados a bloqueios m\u00fatuos durante o treinamento foram solucionados.\n<li class=\"l\"> M\u00f3dulo <noindex><a rel=\"nofollow\" href=\"https:\/\/rspamd.com\/doc\/modules\/rbl.html\">RBL<\/a><\/noindex> substituiu os m\u00f3dulos SURBL e Emails, o que permitiu unificar o processamento de todas as verifica\u00e7\u00f5es de listas negras. As capacidades do RBL foram expandidas com o suporte a tipos adicionais, como seletores, e ferramentas para facilitar a expans\u00e3o das regras existentes. Regras de bloqueio de email baseadas em listas map n\u00e3o s\u00e3o mais suportadas; em vez delas, recomenda-se usar multimap com seletores.\n<li class=\"l\"> Para determinar tipos de arquivos com base no conte\u00fado, uma nova biblioteca Lua Magic foi implementada, utilizando Lua e Hyperscan em vez de libmagic.<br \/>\nA cria\u00e7\u00e3o de uma biblioteca pr\u00f3pria foi motivada pela busca de maior desempenho, a elimina\u00e7\u00e3o de falhas na detec\u00e7\u00e3o de arquivos docx, um API mais apropriado e a adi\u00e7\u00e3o de novos tipos de heur\u00edstica, sem estar restrito a regras r\u00edgidas.<\/p>\n<li class=\"l\"> O m\u00f3dulo para armazenamento de dados no banco de dados  <noindex><a rel=\"nofollow\" href=\"https:\/\/clickhouse.yandex\/\">Clickhouse<\/a><\/noindex>foi melhorado. Novos campos LowCardinality foram adicionados e o consumo de mem\u00f3ria foi substancialmente otimizado.\n<li class=\"l\"> As capacidades do m\u00f3dulo <noindex><a rel=\"nofollow\" href=\"https:\/\/rspamd.com\/doc\/modules\/multimap.html\">Multimap<\/a><\/noindex>foram ampliadas com suporte a <noindex><a rel=\"nofollow\" href=\"https:\/\/rspamd.com\/doc\/modules\/multimap.html#combined-maps\">mapeamentos<\/a><\/noindex> e <noindex><a rel=\"nofollow\" href=\"https:\/\/rspamd.com\/doc\/modules\/multimap.html#dependent-maps\">dependentes<\/a><\/noindex> combinados.\n<li class=\"l\"> No m\u00f3dulo Maillist, melhorou-se a defini\u00e7\u00e3o de listas de distribui\u00e7\u00e3o.\n<li class=\"l\"> Nos fluxos de trabalho, agora \u00e9 poss\u00edvel enviar mensagens heartbeat ao processo principal, confirmando o funcionamento normal. Na aus\u00eancia dessas mensagens por um certo per\u00edodo, o processo principal pode for\u00e7ar o encerramento do processo. Este modo ainda est\u00e1 desativado por padr\u00e3o.\n<li class=\"l\"> Uma nova s\u00e9rie de scanners em Lua foi adicionada. Por exemplo, m\u00f3dulos para escanear mensagens em pacotes antiv\u00edrus Kaspersky ScanEngine, Trend Micro IWSVA (via icap) e<br \/>\n    F-Secure Internet Gatekeeper (via icap), bem como scanners externos para Razor, oletools e P0F foram propostos.<\/p>\n<li class=\"l\"> Adicionada a capacidade de alterar mensagens atrav\u00e9s da API Lua. Um m\u00f3dulo foi proposto para fazer altera\u00e7\u00f5es nos blocos MIME. <noindex><a rel=\"nofollow\" href=\"https:\/\/rspamd.com\/doc\/lua\/lua_mime.html\">lib_mime<\/a><\/noindex>;\n<li class=\"l\"> Foi garantido o tratamento separado das configura\u00e7\u00f5es definidas atrav\u00e9s de &#171;Settings-Id:&#187;, permitindo agora associar regras apenas a determinados identificadores de configura\u00e7\u00e3o;\n<li class=\"l\"> Realizadas otimiza\u00e7\u00f5es de desempenho no mecanismo Lua, na decodifica\u00e7\u00e3o de base64 e na detec\u00e7\u00e3o de idioma para o texto. Suporte adicionado para caching de correspond\u00eancias complexas (maps).
