[otrs] Postmaster filters question.

Hi, I like the "Postmaster Filter" way of handling inbound dispatching/filtering. However, i see a few shortcomings, that i'm not entirely sure is because i'm doing something wrong or because they just don't work the way i "would like them to". First of all, as far as i can see, a postmaster filter is in effect on ALL defined pop3 accounts. I would be very cool, if a filter could be applied to only pop3 accounts "a" and "b" but not "c" and combinations like that. Is there a way to do that, somehow? Second, it seems as if it's only possible to AND multiple matches in a filter, is that true? Any way to OR them? Perhaps features to consider in future releases... ;-) Thanks for any input. -- /Sune
