Looks like the DragonFly Mail Agent (dma), which already has been
mentioned in this thread, could become a decent default for Wheezy+1
after some small changes.

In a nutshell: it's able to deliver locally and remotely, has a queue,
supports TLS/SSL, does not listen on port 25 and instead of running as
daemon, it if run every 5 minutes via cron to flush the queue.  Maybe it
could be changed to use incron and not cron on Linux.  It's
README.Debian contains more verbose information.

It currently lacks support for .forward files, ignores -bs, misses -F,
ignores -om and the newaliases command exits with 1 if run without
arguments.  I'm nore sure if the latter two are problematic.

JFTR: According to [1] and [2], the reason to switch away from smail was
that exim are easier to configure.

If there will ever be a Debian user survey (again?), this question would
be a good fit.  At least GRML did user surveys in the past:
