Well, I'm surprised to say the least.  I have some virtual domains on a
server.  So I did `mail "webmaster@foobar.com"@the.real.host` and sent a
test message.  Surprisingly, to me anyway, I got this on the local host:

Oct  7 14:32:39 miami postfix/qmgr[5717]: D2A605027F:
from=<roberto@miami.connexer.com>, size=364, nrcpt=1 (queue active)
Oct  7 14:32:40 miami postfix/smtp[15855]: D2A605027F:
relay=the.real.host[w.x.y.z], delay=1, status=sent (250 Ok:
queued as DB3DFC603)

Then, on the receiving mail server, it stripped off the @the.real.host
and then proceeded to deliver it to webmaster@foobar.com.  Now, I don't
know the effect if that were a system account, but it certainly works
with virtual accounts.
