Maybe so, but then it's not really a unit test, since by calling it you
have just included an entire SMTP server in the test along with whatever
else you're trying to test.  Still, maybe it's a good idea sometimes.  The
API was created a long time ago, and it's probably not ideal.  It is very
unfortunate that it gives you no way to know when it is really done.

Well...  I dunno what you're testing.  But you could make a fake (verified,
of course) of sendmail() and call that in your tests instead.
