Kmail filtered mail

[Johnny Morano <johnny@life.be>]

Hey all,

i'm trying to backup/restore my mail directory,  but i can't seem to find the 
files/dirs where all my filtered mail is saved in. All my filters are created 
like in the following example:

[Filter #1]
action-args-0=.digitalpimp.directory/slashdot
action-name-0=transfer
actions=1
contentsA=slashdot@slashdot.org
contentsB=
fieldA=From
fieldB=
funcA=contains
funcB=contains
name=<From>:slashdot@slashdot.org
operator=ignore

so, i download my mail via pop in different folders, and then i filter and 
store that mail in child folders. If i just copy the files from my Mail/ dir, 
i dont have my filtered mail anymore...
i know, i could do an strace on kmail, but it's saturday and i'm lazy, can 
anybody help me? thx ;-)
