Migrating from sendmail to IMS 5.2
Hi All,
While I migrate my users from our old sendmail server to our new IMS 5.2 server, how do tell IMS to send mail for unknown users to the old server?
IMS is running in direct LDAP mode.
Each server has an MX record, with preference to the old one, and each accepts mail for the same domain.
Each migrated user will have an entry in the old server's aliases database (user: user@newserver) which will force the mail to be delivered to the new server, but of course the new server won't recognize users who haven't migrated yet.
TIA,
Glo

Trying to have two different mail systems be authoritative for the same domain(s) is trouble some. Fortunately iMS at least 5.2 has something to help you.

Definition
Fully qualified host name of a mail server responsible for handling mail for users
not found in the local directory. Messages sent to users not found in the messaging
servers directory are forwarded to the mail server specified in this attribute. This is
useful when making a transition from one mail system to another and all users
have not yet been moved over to the messaging server directory. An empty or
missing attribute implies the local MTA is responsible for routing and delivering
all messages for users in that domain.

Thanks, Chad! I used Delegated Admin (Mail tab) to add the old mail server as the smart host. Then I had to remove the final rule for selecting local users in imta.cnf (shelley is the new mail server for everybody@library.ucla.edu):
library.ucla.edu $U%$D@shelley.library.ucla.edu
That rule was there, I suppose, because I hadn't specified a smart host during installation of IMS 5.2.
Thanks again,

Easy use the mailroutingaddress ldap atribute.
You need to have all the old-users-server in the new iMS Server and all the old-users-server need to have a mailroutingaddress atribute with the old-user-server email address in the file (the mail address have to be mailhost.your.domain.)
