Hey Luis, make sure the domain subscribercentral.com is in a recipient policy, if not add it. Exchange Organization >> Recipients >> Recipient Policy >> Your Policy Under policy properties, E-mail Addresses (Policy) Tab, add a new generation rule as SMTP address, with your domain as the address like this: "@subscribercentral.com". Make sure the "This Exchange Organization is responsible for all mail delivery to this address." option is CHECKED. from the help >> - Use this check box to make the Exchange organization responsible for all e-mail delivery to this address. Hope this helps. .frihani Sent: Tuesday, February 26, 2002 1:54 PM Subject: [exchangelist] Setting up a 2nd domain... > We have 2 domains here: dconx.com (our primary domain) and > subscribercentral.com (old domain kept mainly for the e-mail addresses) > > Most users here have e-mail addresses in both domains in their AD e-mail > list. > > I'm trying to get E2K SP2 to accept mail from the subscribercentral.com > domain and deliver it to the right person.
