Depends on the ISP involved.

The mechanics of this are that an "MX" record for the given DNS name is
inserted in the domain tables.  This record causes mail to be forwarded to
the machine specified.  That is *all* that a MX record can do -- the rest is
up to the software on the target host.

What MCSNet gives you a choice of is as follows:

1)	You can map all email for a given domain to a single mailbox.  This
	is done by some software we added to the mail transport such that
	the system "spoofs" the address, and thinks it has many (hundreds)
	of "names".  The mail is then redirected to the appropriate user
	box.

2)	You can leave off the last step (redirection to a single mailbox)
	and do what we call mapping the domain "local".  Taking this option
	is equivalent to aliasing your domain to "mcs.net"; that is, if
	someone sends mail to "karl@yourdomain.com" I will receive it!  If
	you have multiple accounts under a domain, this is your only (and
	best) choice at the present time.

	This allows for *multiple* delivery points, *exactly* as if you were
	using the local accounts.  What you *cannot* do with this is, for 
	example, have a "sales@yourcompany.com", because the "sales" account 
	already exists here.

If you need "fake" email aliases (like "sales@yourcompany.com") the best 
bet is to use option (1) with something like procmail or filter to further 
distribute the mail on your own.
