VRFY to verify destination accounts

Hello,

I use some servers with Postfix as mail gateways/relays to perform
filtering/virus scanning to incoming emails.
I don't have a list of users of the destination servers and is not
possible to build a LDAP/MySQL...server to store them.
The problem is that I don't want to accept emails without know if the
destination user exists in the destination server.
Is there anyway to for example, use the VRFY command to verify if the
account exists? Can Postfix do this verification and reject the mail if
the answer is negative?

Thanks!
Regards,
