Archiving e-mail, access via web?
 

I've been thinking about e-mail archiving lately. My ideal solution would be a web-based package, some searchable database of all my messages that would be accessible from any workstation. (That would enable me to link to specific messages and threads without copy/pasting message text into wikis, our information system, etc.) Tagging would be a nice feature as well since many messages overlap into several categories.

Has anyone come across a package like this?
