I do wish there was a nicer mail client available for Linux though. KMail is the better one I've tried, but Apple Mail is still the one thing I miss from my Mac days. I know function is key, but the Linux mail clients are all just so *ugly* to use.
@nigeldgreen err. Thunderbird?
That's the one I use and, to be fair, it does do exactly what I need. I'd be very happy if it just had a decent implementation of 'vertical view'.
