Yes - from what I remember opening files is relatively expensive.
I have'nt looked at the exim implementation of this but I would have thought
a match on a given address using a linear search could be done on a single pass
of the file (whether its a domain or a full address). A match on a indexed file
would require two lookups, but that would be quite cheap.
