I would let to set the ".co.uk" domains up on my server, but simply have them forward to the ".com" page.
What I do in this cases is open the virtual site in the server as any regular site. Set a "re-directioning " java script* (after the message you'll find a copy) in the sole index file pointing to the other site.
It would be helpful if any email could forward too, but this is not essential.
Open mail accounts in the regular way for domain 1 and have them forwarded to domain 2
* java insert (without quotations) :"<script language="javascript"> setTimeout("window.location = ('http://domain2')",100) </script>"
insert this after the body tag in a regular html file, name it index.html and upload it to domain 1
Hope this helps. Easy and clean. Regards Jorge CeballosDesde-Mexico.com es el catálogo de productos y servicios mexicanos para el mundo. Permítanos hacerle su catálogo electrónico y apoyarlo en sus ventas alrededor del mundo.
