Hi,
Recently modified qmail-inject.c to perform address rewriting. This
allows to get all To:, From: etc. into our standard format. Thought others
may be interested. Anyone who knows qmail-inject inside out (Dan?) care to
comment on it? Cheers. (There's still some diagnostics in this version,
but you get the idea.) (Sorry about the comments, Dan :-)
