Log message:
~/.forward files handling was fixed recently so that it is the privileged
process that does the opening, this commit does some cleanup, and fixes a
bug I experienced today which was caused by a use-after-free.

I did some testing to make sure a user cannot cause smtpd to deadlock, or
loop, with broken setups (self-referencing forwards/aliases, empty files,
broken files...), but if you are playing with aliases/forwards PLEASE let
me know of any bug you run into.
