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.

  - Document how to use procmail as a filter (not as an MDA; that's easy
    enough).

  - When reading an UIDLS file that contains unsorted UIDs: don't sort them 
    anymore, but assume that the file is corrupted. The only mpop versions that 
    wrote unsorted UIDs were 0.4.2 and 0.4.3. 0.4.3 was oboleted by 0.5.0 on 
    2005-03-15.


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
