The following things are planned:

  - Write a generic filter script that extracts some information from the mail
    and allows simple rules, for example regex matching.

  - When reading an UIDLS file, don't test whether the uids are sorted
    anymore. The last version that wrote unsorted UIDLS files was 0.4.3.


The following features might get implemented some day:
  
  - Add support for enhanced response codes for better error messages


The following features will probably never be implemented (because fetchmail or
getmail are better for it):

  - multidrop
  - daemon mode
