kmail hangs

[Marcel Janssen]

Hi,

I have some problems with kmail.

Basically it just hangs when :
1) just after waiting some time (not touching a thing)
2) going to Settings->configure kmail->Accounts.
3) When I start kmail and just let it sit there, sometimes it wil receive 
mail, but when I click the "check mail in" button it will hang.

It only happens on this specific user account so I guess it's setting related 
or the extremely large mail box may cause issues.

Anyone knows a solution ?

regards,
Marcel
