Thanks - I appreciate the advice.

The reason we can't use a lookup table is that we're faking local domains
(in order to convince an uncooperative application that we really have
"unique" emails for each user).

So I might be better off with regexps in my rewrite, such that for any
address which ends in \.FAKELOCAL\.[0-9], rewrite to remove the fakelocal
domain and deliver.

I suspect that would be a lot more efficient than the original approach -
was that why you think I'd be better off keeping it internal to exim?
