I hope this is /dev/null...

That's a common mistake to think that Sendmail, as Mail Transfert Agent, is
responsible for delivering the message. That's wrong : alias expansion is the
responsability of the Mail Delivery Agent, which is another program
like "deliver" or "procmail". Thus, I dont't think that the Sendmail process
that is located *before* MailScanner should be modified in a way to support
alias expansion. What is correct would be to use the "access" database in
Sendmail in order to reject mail if matching a rule.
