hi
we plan to migrate our root domain sub domain setup to one central ad domain.
atm we got a exchange dag that hosts all our mailboxes, we want to accomplish a setup where we can migrate each user to the new ad forest/exchange...
the problem is email receive we got a ironport that delivers the authorative domains to the exchange server via @domain mappings
if we move an user account to the new domain the emails get delivered to the old domain/exchange server...
does anyone knows a tool or method to route emails to a exchange server based on the emailaddress of the user not the whole domain?
all tools/email relays we found can only route whole domains to a server not single email addresses
we looking for something we put between our ironport and the exchange servers that listens on port 25 accepts all incoming mails and route it to the new or old exchange server using a list of emailaddresses
for example:
user1@domain1.com is migrated to the new ad forest and got a mailbox on the exchange server sam account name and emailaddress is exact the same as in the source domain...
our ironport receives mail for this user and delivers it to the "tool"...the tool look on his list...if user1@domain1.com is migrated to the new domain then it delivers the email to the new exchange server in the new forest if not it delivers the mail to the original source forest
thanks
