[LUAU] Your favorite hostable webmail?

[Jeff Mings]

Hi guys!

    I'm wondering if any of you have been using a good webmail server
hosted on your own server(s) that you really like.  You know, something
that users can run in their browsers for full email client functionality.

    I am interested in deploying this on a Linux server with several vpn
tunnels to remote locations.  Most users are on Firefox and there's no need
to support the myriad weirdnesses of Internet Exploder.  Any good or bad
experiences out there?

Thanks,
-Jeff
