Currently we are using on stmp address for this environment.
Since our company will separate to some subsidiary and we determined to manage each organization with OU.
We have to assign separate smtp email address for each subsidiaries.
We will keep current smtp address for a while to recieve email from customer who don't know our email address change.
We are planning to assign smtp address as follows,
but one of subsidiary has to use,
Looks hosting and recieving multiple smtp name space is not a big problem but I'm worried about "sending". I know on ADUC, we can set which smtp address should be primary, but we are going to manage AD with OU. Is it possible to assign primary smtp address based on OU?
Or are there any concern about this operation?
