I have good experience with exim4, the default config needs some
tweaking (at least under Debian) for SSL and AUTH stuff, but that is
fairly documented and not difficult to setup. I only have one "upstream"
provider, a so-called smarthost, so I need not fear it will break with
any other mail host. YMMV.

Of course running exim4 only for mail-forwarding is a bit like hunting
sparrows with cannons (or whatever the equivalent english phrase is :-)
but then, it gets the job done, and without any mail in the queue its
memory footprint and cpu usage are neglible.
