What confuses me is that in the first section it *does* (or at least

met (i.e. does NOT match the regex) it delivers to INBOX/Possiblespam.
Because ALL of the NOT conditions evaluate true. They're ANDed.
You may need a refresher in boolean logic.
If a condition matches ("true"), then assign a value of 1, otherwise 0.
1 AND 0 = 0 (skip action)
0 AND 1 = 0 (skip action)
0 AND 0 = 0 (skip action)
1 AND 1 = 1 (take action) only when BOTH conditions match
In an OR logic - which one might normally use scoring for in procmail (see
'man procmailsc'), a lot more paths lead to taking the action:
1 OR 0 = 1 (take action)
0 OR 1 = 1 (take action)
0 OR 0 = 0 (skip action) NEITHER condition matches
1 OR 1 = 1 (take action)
Using scoring, you can specify something like:
:0:
* 9876543210^0 ^TO_kiddie2\@(mymail|mydomain)
* 9876543210^0 ^Received.*for..kiddie2\@(mymail|mydomain)
INBOX/Kiddie2
Which will stop evaluating conditions as soon as one evaluates true (the
number exceeds the "maximal" scoring value - otherwise, all the conditions
would be evaluated, and as long as the score result was >0 when done, it'd
take action).
BTW, it really appears as if you're using procmail as an MTA - trying to
deliver mail intended for different users of a system (via your "catch-all"
address). If this is the case, it's time for the procmail
mantra: Procmail is NOT an MTA. You'll run into all sorts of problems if
you try to make it work like one - chief among them will be when you
receive a message destined for more than one user of your system (work
through your logic and see what'll happen).
