I am trying to create a procmail recipe for my email server. What happens is that I am using a maildrop box, but the ISP strips the envelope header. I have another header (X-prepostini-address that can tell me who it should be delivered to. I want to match the user and then forward to them. This is what I am trying right now.

:0
* X-prepostini-address: *\/[^ ].*
! $MATCH


Can someone please give me a hand.

Thanks
Jeremy
