I don't have a ton of Postfix experience, but using this Postfix FAQ
question ( http://www.postfix.org/faq.html#incoming ) as a template of sorts
(and reading bits from the O'Reilly postfix book and the postfix man pages.

You would create a transport map file, say /etc/postfix/transport. Add
entries for the domains you want to limit and assign them to a transport
name, let's say lamdomains

yahoo.com          lamedomains:

You need to then run: postmap /etc/postfix/transport

Then in the postfix main.cf, add lines to tell it about the transport and to
tell it that anything in that transport has the recipient limit.
transport_maps = hash:/etc/postfix/transport
lamedomains_destination_recipient_limit = 5

So now you've created a transport, put some domains in it, changed the
default behavior of postfix for that transport, you just need to tell
postfix what to do with that transport (aka, deliver it with smtp).

Add a line to master.cf:
lamedomains      unix  -       -       -       -       -       smtp

Now tell postfix to reload it's config: postfix reload

Again, I haven't tested this, so you mean need to read man pages and play
with that a little, but that should set a postfix user in the right
direction
