Is it possible for exchange to accept mail to any domain, and deliver it to user@xxxxxxxxxxxx I think I better explain. Our mail server is accessed in different ways. Before I install another exchange box, I'd like to be sure of the following. To those on the same subnet, it's accessed by IP address..... *old school I know, but we like it like that* i.e. user@xxxxxxxxxxxxx To those on the same LAN, it's accessed by internal DN, which is mail.box. user@xxxxxxxx To those on the internet, it's accessed by FQDN user@xxxxxxxxxxxxxxxxxxxxx Is it possible to for the exchange box to accept mail for in all these ways for the intended user. And please don't assume my client setup, we have Mac boxes, Linux boxes, damn, we even have a Amigo box, so deliver is done via many MTA's. Any help would be appreciated. Also, a quick question, why does an AD box running DNS assume that it's the top of the domain? My w2k server is w2k.domainname.com but it assumes it's domainname.com and this causes problems when people attempt to access the webserver internally. I've tried editing the DNS record, but it doesn't let me. How do I add and remove hosts from a windows box?
