High Level-Goals

• lower resource usage: higher throughput and lower memory usage
• higher accuracy: lower FPs and lower FNs (rules, rules, rules... this also includes some notion of speeding up the mass-check process)
  

High Level Anti-Goals

• features: extra options, non-critical changes not related to the above goals, etc. (except perhaps in plugins)
• option bloat (except perhaps in plugins)
  

Basic reorganization of rules

• SVN external for rules (using "if" for version-specific rules)
• separate 50_scores.cf into input and output files
• traversing configuration directories
  

Memory Usage

We should probably evolve some understanding of what we want to convert to plugins. Here's the list:

• finish transition away from AWL and finish replacing with "History" plugin including backwards compatibility
• plugin-ize Bayes
• move user preference configuration code to plugins
• plugin-ize whitelisting
  

Performance/Speed

• Predictive autolearn? do check before bayes_check, if we are likely to autolearn, go r/w instead of r/o. Can implement on first bayes_check call.
• Don't bother caching full/decoded/etc at start in PMS. how much caching do we do now? multiple times in PMS? may not be an issue due to references.
• short circuiting ideas:
  • set certain rules as SC if hit
    • USER_IN_WHITELIST, USER_IN_BLACKLIST (not DEF)
    • BSP
    • HABEAS
  • allow SC on ham score (ie: < #)
  • allow SC on spam score (ie: > #)
  • should autolearn skip SC msgs? should we always do autolearn in the appropriate direction?
  • AWL should be skipped during SC
  • SC rules should have a negative priority so they run first
  • do *not* do score check per rule, do it either per priority or rule type (header, body, etc.)
  • SC will require is_spam SC as score + required_hits will be at odds
  • add SC header macro (get_tag)
  • SC for S/O 1.000 rules? how about S/O near 1? BAYES_99, etc.
  • Some form of order/priority rearrangement:
    • Blacklist: short
    • Whitelist: user/admin wants it
    • BSP/Habeas: reputable, non-forgable
    • Other SC Rules: as early as possible
    • Other Local Rules: lightweight
      

Accuracy Ideas

• network test, do DNS lookups on the HELO (A, NS, and SURBL)
• network test, do DNS lookups on the EnvelopeFrom (SURBL)

Goals

There are no currently defined release goals for new versions beyond continued bug fixes and enhancements as discussed on the development list and through bugzilla.

Release Schedule

The Apache SpamAssassin project goal is to produce three major or minor release per year with release candidates proposed on or closely to January 30th, April 30th & September 30th of each year.

Release Support

A major release is supported for no less than 6 months after the release of the next major release.

This means that as of July 27, 2010, all versions prior to 3.3.0 are considered unsupported and when 3.4.0 is released, 3.3.X will be supported for at least 6 more months.

Old Release Goals

• 3.1.x
• 3.2
