No. Sorry, I didn't make myself clear.
My situation is:
Mail from Web -> Hits Account -> Collected by dedicated server -> Filtered by
SpamA on dedicated Server -> Transfered to KMail by pop3 through dial-up
line, Wlan or whatever is available.
Thus filtering is done on another computer.
I don't filter spam with KMail. I use KMail filters only to sepperate
different mailing lists.
These mails slipped through the filtering infrastructure and were downloaded
by KMail. After downloading the mails, CPU load raised up to 100% for a few
minutes. Selecting, Moving, etc. of these mails raise the cpu load up to 100%
as well. KMail was complete unusable until a delete the mails with "rm
Mail/inbox/cur/$mail"
Keep smiling
