well I looked at the code, it's definitly the parent, but I do still see
the memory increase over time:

   procs                      memory    swap          io     system     cpu
 r  b  w   swpd   free   buff  cache  si  so    bi    bo   in    cs  us sy  id

 1  0  0  18664  21200  17184  61280   0   0     0   297  152   169  62 38   0

just a bit later:

 0  0  0  18820  30736  17724  60300   0   0     0    30  102     9   0  0 100

swpd is up.

although not the size of MailScanner, so it aint it, then how the hell did
I get the memory/swap get exhausted. There is one very simple explanation,
I guess:

rsync (backup) + the size of the quarantine-directory.

I'll blame that for now.
