Coexistance

[skulty]

Hi,

We currently have a very old AS400 IBM AnyMail server (mail.foo.com)

We have installed a scalix mailserver (email.foo.com) (
This server is working, sending internal mail and external mail. It is not accepting mail due to the old email server bouncing accounts that are not on its machine.)

I would like them to coexist for a while.

I could get the old email server to forward certain users email to the new scalix server, however that is very time consuming (you have to setup the users as remote..yada yada).

I would rather setup the scalix as the primary email server via MX records and demote the old email server. Then any mail coming into the domain and to the scalix server, that there is not a user account setup for, would be forwarded to the old email server.

That server would then deliver the message to the client.

The accounts on both servers would be different, hence an email would be sent to the scalix server according to the MX records, if it cannot be delivered, it would be forwarded to the other server.

Can i set this up?

Any help is great

Thanks

Hi Skulty,

This is pretty straight forward to setup. In Scalix, if a message is received for an unknown Scalix recipient (i.e. as400-user@foo.com), it will be handed off to sendmail. Sendmail then checks the /etc/mail/local-host-names file and if it has foo.com in it, it will bounce the message. However, if foo.com isn't in that file, it will do a lookup of foo.com and if you've configured it to be mail.foo.com (either through the /etc/hosts file or via DNS), then the message will be handed off to that machine.

Thanks,
Rachel
