Hi there,

We are in the process of migrating an organisation from Exchange 2003 to Kerio. My main question is this:

We migrate a single user to Kerio. External email gets delivered to them fine. If the email is to anyone else it gets forwarded to the exchange server fine.

The problem is, if a user on Exchange emails him, it will not end up in his Kerio inbox as exchange delivers it internally. if I remove his addresses from exchange it bounces.

How do I get exchange to send internal email via the Kerio server so internal exchange users can email migrated users?

Ideally I could get the exchange server to send all emails, including internal ones, through an external DNS, but I cannot find how. Surely others migrating must have found similar?

Thanks,

Sam

I wanted to do the same thing and got it working. I just typed it all in and hit post reply and it disappeared. ugh! so I will write it again.

1) In DNS on your domain, which we will call mydomain.com, setup a new subdomain called km.mydomain.com
create a record of email.km.mydomain and point it to your kerio server address
2) in kerio, create this sub domain so it can get email
3) create users in the sub domain that will be used as forwarders
in my case, I named them tomforward<_at_>km.mydomain.com
4) set that email account to forward to the main email account you want it to go to on the kerio server
in my case, tom<_at_>mydomain.com
5) on your active directory server, in users and computers, create a new contact and call it tom-kerio with an email address of tomforward<_at_>km.mydomain.com
5) on that same server, go to the main email account, tom<_at_>mydomain.com, and tell it to deliver messages to both it and to the tom-kerio contact

Now when someone sends an email to tom@mydomain.com it gets forwarded to tomforward@mydomain.com which in turn forwards it to tom@mydomain.com. You would think this would be an endless loop, but the kerio server knows there is a local tom<_at_>mydomain.com and will deliver it locally on that server.

This has worked very well for me. I hope this is clear and it helps you.
