What's this?
============

This plugin is intended to delete all emails expired automatically.
User can set an expiration for each mail folder.

In contrast to the well known "proon" plugin, this plugin runs 
independend of the user login at daily cronjob time. 

If you've setup spam filtering and do not automatically delete 
those mails (e.g. using "maildrop" or "procmail") or you're not 
allowed to delete those mails because of external or internal policy
restrictions, the only possible solution is to move those mails 
into "Trash" folder (or a special "Spam" folder). 

Without automatically expiration and users only logging in 
infrequently, the folder size will increase quickly and consume 
a lot of disk space.


Limitations
===========

This plugin version has some limitations:

- IMAP server running on same server as SquirrelMail
- IMAP server uses "Maildir" format to store message
- Works only for systems where mail users are synonymous with
  local users (it does not support virtual systems)
- You need an access level to the server high enough to be 
  able to install a system cronjob
  
If you know a way to solve those limitations, feel free to modify 
the code (e.g. support for "mbox" (or any other) mail box format).
Let me know, and I'll add the code in an upcoming release of this 
plugin.
