[PLUG] "self-addressed" spam filtering

I use kmail as my POP mail client.
kmail's spam related filters appear last in the processing order.  I have a 
filter called "people I know" that moves mail from addressbook contacts to 
a "people I know" folder.  That means that messages appearing to be from 
myself (in my addressbook) do not get filtered for spam.  That means spammers 
who forge the "from" address to match the "to" address end up in the "people 
I know" folder.

I had been using a filter that checks "from to see if it is supposed to be me, 
and if so, the "to" and "organization" headers. Ff they don't match, the 
filter marks the message as spam and executes the appropriate bogofilter and 
spamassassin commands for training.  That worked as long as I was using kmail 
to send all of my POP messages.  

Recently, I have had the need to occasionally use a webmail interface.  There 
is no way to set the organization header when sending via webmail, so all 
copies to self sent via webmail end up marked spam.  I have had to delete 
this filter.

I then tried to set up a filter that tests the "from" as containing my address 
AND neither the organization not containing "Alexion" NOR the body including 
text from my webmail signature... but I couldn't find a way to mix "and" 
and "or" tests in a single filter.  

I was thinking of using two filers instead: First test the "from" as 
containing my address, then pipe through a filter that tests for either the 
organization mismatch or the sig line mismatch.  Is this possible with kmail?  
How?
