I've stayed with Kmail through all the dreadful upheaval from V3 to 
v4, but now I'm seriously considering jumping ship to Thunderbird, 
which I've been trialling with a dual POP feed for several weeks.

It's not as feature-rich as Kmail, but seems reliable and is also much 
simpler to clone onto another installation.
