I'm using mutt to read my mail through IMAP4_SSL... But currently it lacks of a cache system, so dealing with big folders (~2000) is quite hard for it.

That's why I hacked an archive utility script to better fit with my needs. The original one is here_. The purpose is to move old mails on subtrees of the folder we want to archive, sorted by month.

I mainly added an option relating mail dates comparisons. So now there are two possibilities :

- believe IMAP dates (appearing as timestamps in beginning of mail filenames) (default behavior)
- believe `Date:` Mail header (-m option)

Use-case :) ::

   $ ./mdirarchive.py -m respyre
   $ tree ~/Maildir/.respyre* -L 1
   /home/phil/Maildir/.respyre
   |-- courierimapacl
   |-- courierimapkeywords
   |-- courierimapuiddb
   |-- cur
   |-- new
   `-- tmp
   /home/phil/Maildir/.respyre.2003-06
   |-- cur
   |-- new
   `-- tmp
   /home/phil/Maildir/.respyre.2003-09
   |-- cur
   |-- new
   `-- tmp
   /home/phil/Maildir/.respyre.2003-10
   |-- cur
   |-- new
   `-- tmp

There is now a subfolder per month. Check script online help for more options.
