I'm not sure what you mean. Do you think about a plugin which checks the
existence of a recipient by asking the "real" mail server? The idea has
been brought up in the past, and it has been suggested doing this check
e.g. via SMTP to the "real" mail server, which would make it independent
from the type of mail server used. I'm not sure if such a plugin has been
written yet.
If you can export a list of valid useraccounts from your "real" mail
server, it might be easier to use a plugin which just checks recipients
against such a list. Such plugins are available as far as i know.
