Help! - KDE4.2 from Factory - KMail starts on logon

Help! Kmail keeps starting up on logon which stalls KDE startup for a bit and then dissapears into the background.

If I start kontact then mail is not contained within kontact but runs as a seperate program.

Killing the kmail process before starting kontact fixes this behaviour, but I have to do this after every reboot or logon.

Can anybody help me as this is happening on both my openSUSE 11.1 laptops.
