Rspamd 反垃圾邮件系统

Rspamd是一个反垃圾邮件系统，因为使用事件模型和正则表达式优化，其设计工作速度比SpamAssassin还要快。目前推出的功能： regexp规则过滤的不同部分的信息;一些内置的功能分析的信息;模糊哈希支持; SURBL滤波器;电子邮件和性质表支持;控制界面进行远程管理和统计信息收集，一个Perl和卢阿插件系统;统计支持（定向结构刨花板/簸扬） ;兼容SpamAssassin ;和一个客户端程序的电子邮件扫描。类似的规则， rspamd约10倍SpamAssassin 。

Rspamd 0.9 发布了，下载地址：https://rspamd.com/downloads/rspamd-0.9.0.tar.xz

该版本改进内容包括：

* Add support of the fast and secure protocol level encryption:
   - curve25519 is used for key exchange;
   - chacha20/poly1305 cryptobox construction for bulk encryption;
   - zero latency overhead;
   - encrypting and balancing HTTP proxy worker
* Rework expressions and create new expressions library:
   - aggressive optimizations based on the abstract syntax tree;
   - abstract expressions support (regular expressions, functions, lua modules
       composites and so on)
   - New comparision and '+' operators support
   - New greedy algorithm to minimize execution time of expressions and
       all symbols
   - Dynamic expressions benchmark and reoptimizations
* Many improvements to the LUA API:
   - reworked logger module allowing to do pretty print of the most of lua
       types (including tables and userdata classes)
   - reworked lua redis and lua HTTP to support more features
   - added opaque type for passing large text chunks without copying
   - new regexp module with many auxiliary functions (e.g. `re:split`)
* LuaJIT is now the default requirement for rspamd allowing to speed up lua
   execution by a large margin (however, plain lua is still supported)
* New plugins:
   - spamassassin rules plugin that allows to load and re-use the most of
       SA rules natively
   - DMARC plugin that evaluates SPF and DKIM policies to the domain policies
   - many old plugins has been reworked to implement new features and improve
       stability
* New aho-corasic trie implementation from @mischasan that allows to load and
   use hundreds of thousands of patterns with no influence on load
* Support of PCRE JIT and PCRE JIT fast path modes that significantly improves
   the performance of regular expressions if supported by PCRE
* New URLs parser and extractor:
   - removed legacy code that was useless for url finding
   - reworked algorithms of URL parsing for more precise and accurate results
   - added top-level-domains tree from http://publicsuffix.org
   - improved emails parsing
   - removed many phishing false positives due to TLD tree check
* New statistics infrastructure:
   - created a separate layer of statistic library
   - improved OSB-Bayes by re-weighting tokens according to the original
       academic paper and `crm114` implementation, which reduced false positives
       rate significantly
   - created learn cache to avoid double learning of statistics and providing
       an efficient way to re-learn class for a message
   - created abstract layers for different statistics backends
   - implemented new tokenization algorithms with fast or secure (siphash)
       hashes to generate statistics features
* Reworked utf8 tokenization that previously corrupted all UTF8 words (minor
   incompatibility with old fuzzy hashes with utf-8 symbols)
* SPF module has been completely rewritten to support complex cases of
   `include` and `redirect` within SPF records
* DKIM module now supports multiple signatures
* Controller passwords can now be stored encrypted by `PBKDF2-HMAC` in the
   configuration file
* Many hand-written HTTP clients has been replaced with the common rspamd
   http module
* New test framework:
   - import lua `telescope` test framework
   - add unit tests for many rspamd modules and routines
   - create a unit test for each possible bug found
   - use luajit ffi for testing C code
   - added preliminary support of functional testing by creating tasks from lua
* Randomize hash seed to avoid certain hash tables vulnerabilities
* Documentation improvements:
   - added documentation for the vast majority of rspamd modules
   - added documentation for rspamd protocol
   - added documentation for the most of rspamd LUA extensions
* Fixed tonns of bugs and memory leaks
* Added tonns of minor features
