how to add the map mail.aliases

[Cindy Xin <cindy_(_at_)_cvs_(_dot_)_openbsd_(_dot_)_org>]

Thanks for all the response.

I tried to add the aliases map in /var/yp/Makefile*...
My problem is: I don't know how to build this map in Makefile.map.
I simply copies the lines under
	hosts.time: $(DIR)/hosts
and change the hosts to aliases, but the aliases map doesn't work.

Can someone give me an example?

Thanks in advance...
