Scott You would need an A record for mail.def.com I would recommend using the Recipient Policy to add the email addresses, not manually via ADUC.

We have a domain let's say abc.com. All email comes to our email server for users@xxxxxxxx Our company has changed its name and now wants both emails to work using the same exchange 2000 server i.e. users@xxxxxxx and our new domain users@xxxxxxx We make changes to our DNS servers which are pulled by the local ISP and I created a new zone for def.com with the following records: MX mail.def.com A www.def.com A webmail.def.com The WWW works fine because I created a host header for def.com in Internet Services Manager for our web site abc.com...so when I type www.def.com it points to our production web site. However, email is does not work from external email accounts. For example under my user account I added in the email address ME@xxxxxxxxxxxxxx I send email internally to me@xxxxxxx it works fine...but using my yahoo account I get undeliverable messages when trying to send to me@xxxxxxx I suspect that more configuration is required on the Exchange server side...but what? Does anyone know? I think I may have to use the Recipient Policy to add the new domain...is this correct? ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: markfu@xxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx
