Migrating from one server to another

[lscala]

Hi there, i'm migrating from my ISP's mail server to my own mail server installed with Sendmail. The problem here is with the non-migrated users. In both servers the domain configured is 123.com, and when one migrated(in new server)user try to send a mail to a non-migrated user(in the old server), my new server responds "User Unknown". That's obvious because the non-migrated user is not created yet. In Lotus Domino, there is a "if the user is not in the local directory, send the mail to this relay server:" field. You put your old server in this field, and the problem is solved." .

My answer is: there is a way, in sendmail, to configure that all mails destined to a user that is not in the local directory, but has the same domain, be redirected to a specific server?.

Thanks in advance.

Luciano.

You should have an "aliases" file in our mail folder (/etc/mail, for example)
In that file, you'd have to add individual entries for those whose mail account is on a different server.

Example:

# Domain specific aliases

joe:            joe@server1.123.com
mary:           mary@server1.123.com
jill:           jill@server1.123.com

Once they are migrated to your new server (and have a local account), just remove their entry.

Any changes to this file need to be follwed by the "newaliases" command.

That's exactly what i thought, but the old server is administrated by mi ISP, apparently supports several domains in it and the FQDN is not server.123.com but server.abc.com, and my users, for example joe@server.abc.com is not recognized as a user and the answer is "relaying denied".

Thanks, it will be very very appreciated if you have any other idea.
