Well if the address is on the same server as yours, you could probably grep the /ect/passwd file as well as the /etc/aliases and /etc/mail/vitusertable files. (and that's assuming that those are the only files your sendmail system is setup to work with).
The real truth is that you can't check without sendint it an e-mail and seeing if it bounces.
