Sensible Email

After the nth time that ThunderBird lost track of some unread email, I got frustrated and wrote this package.
It's main goal is to be RELIABLE and not imitate the self-corrupting database system that ThunderBird uses.
I also wanted it to be faster, and easier to use.

Version: 1.1.0

The featurelist currently includes:

• SMTP and POP3 support
• All communications with the mail servers is done in a seperate Server process, and doesn't interfere with or slow down the UI.  (Note that it is possible to put the Server process and Mail repository on a separate system.)
• Email is kept in a SQL database.
• Attachments are automatically extracted and saved in a directory tree - and will be deleted when the message is deleted from the system.
• Message filters can be quite complex, and may be collected into Groups of filters for easier maintenance.
• Tags are user definable, and are also an integral part of Filtering.  Adding/Removing tags from msgs can also add or remove those messages from folders they are in.
• A message may be in multiple folders - without making copies. (they are linked)
• You can set preferences to control which version of a message you would prefer to see, HTML or Plain Text - as many message arrive in both formats.  (and you can always see the other format easily, as well as headers.)
• Wizard makes creating filters from a message for a Mailing List extremely easy.
• Uses your ISP's SPAM headers (if available), or you can install SpamAssassin's "spamd", and that will be used.  Customizeable trigger levels for SPAM and potential SPAM (Fishy messages).
• Search starts with the most recent message, and works backward through time - so you don't need to wait for it to search through all 3000 ancient msgs before it gets to the ones you are currently interested in.
• Search result lists are just like the usual email msg list, and you can do all the same operations on the messages.
• Multiple lists of messages may be displayed at once.
• There is a full redundant backup of all received (and imported) email in a standard "mbox" format file.
• Built on the Eclipse RCP framework. 
• Open Source

Downloads: (other platforms available just ask  - pretty much anything that Eclipse will run on.)
