Team, I am new to Exchange 2000. I am looking to see if one Exchange 2000 email server (or other product) can handle multiple local domains; (Currently I inherited a position that has WorldMail running, and I would like to reduce my headaches by as much as possible, therefore I must do away with it immediately!) For Example, I would like to have the following: sub1.domain.com sub2.domain.com sub3.domain.com, etc... (up to 100?) Each domain should have its own users with email addresses such as: "user@xxxxxxxxxxxxxxx"; In addition, is it also possible to delegate permissions to one user (power user) who can remotely administer their "sub2.domain.com" user mailboxes (create, modifiy & delete)... All advice is greatly appreciated, thank you in advance... richard
