There is a perl library you may find helpful: File::Tail. There used to
be a popb4smtp.pl script out there that I found useful for such things.
It seems that the owner of it has lost his webspace. I have a copy if
you would like to see it. I was able to modify it to use a db backend
instead of just touching files so it can be used in a multi-server
environment. I can send those modifications as well if you are
interested.
