I am looking for a locally hosted web based mail client that will work on Windows (Vista and up) as well as Linux. Right now, I use mutt (Cygwin mutt on Windows), but I was wondering if there was a simple web based client I could use. It does not need all of the fancy features of mutt, just the ability to send mail and allow me to browse my local mbox files.
I personally use Squirrel Mail, which is provided by my web hoster.
Alternatively, you could use Gmail to manage your own personal email.
