I think I found out. This is a Horde problem (found it in 
bugs.horde.org) (well, to be prefectly honnest, it's a sieve bug, which 
simply can't compare with negative numbers...  but the good thing is 
that there's a fix.

I installed the patch on my server, and will let night mails come in to 
see how things are going on.  Will let you know for sure.
