Not to be picky, but the filename is:   /etc/aliases
and remember to run the command "newaliases" after you make changes.

You can easily configure sendmail to accept mail for multiple domains.
just add the domain names to:  /etc/sendmail.cw

As far as "virtual hosting" with sendmail, I don't know any easy way
to do that.  You could probably reprogram the sendmail.cf file to
handle it, but sendmail programming is very cryptic and difficult.

It would probably be easier to program procmail to separate out 
the different domains and forward them to the correct recipient.
Personally, I've never used procmail, so I can't help you there.
(that's what I'd try first, if it was me)
