i own two domains: www.abc.com and www.cba.com (for example). i finally set up all mail account needed at www.abc.com but i need the same accounts at www.cba.com is there a way the map cba.com to abc.com? all domains are behind a NAT router and point to the same ip address (eth0 on my raq550).
standard mail alias stuff - set up the users on the 2nd domain with whatever login names you want, set up the aliases for them with the desired names.
there's no good way to "bulk import" mail account settings per domain, especially if the domain you're "copying" from has the desired names as the actual user login names, rather than as aliases...
