The problem is less one of mailboxes than one of domains. You're -- I presume -- sharing a single domain across the two servers. Because of this, each server needs to know that it is not a "one-stop shop" for the domain, but that there is another server with additional mailboxes. On the Imail side, this can be done by creating aliases for each Exchange user targeting a special "routing domain" in the Exchange orgnization such as @exchange.example.com. Aliases are checked before users, so it doesn't matter that there will also technically be a username with the same address (since the user is in AD). Mail for those aliases will be routed off-box before it gets to the local mailbox, so the mailbox is effectively disabled. On the Exchange side, this can be done by creating Contact objects for the Imail users, as above, or by using Recipient Policies to steer mail for unknown users off the Exchange box to IMail. My exchange2aliases script (see my sig) is designed to synchronize Exchange users into IMail aliases. If you manage your AD right, it can be used to automate part of the process, creating IMail aliases for any user that has a mailbox in Exchange. I can explain further if you're with me so far. --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.imprimia.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.imprimia.com/products/software/freeutils/exchange2aliases/download/release/ http://www.imprimia.com/products/software/freeutils/ldap2aliases/download/release/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
