I am currently evaluating Exchange alternatives and like Kerio Mailserver very much. However, I have ONE really important need:
I need to host SINGLE users on several domains on the Kerio Mailserver. These domain's MX records do not point to Kerio, but to another mail server.
Desired Distribution scheme:
user1<_at_>domain.com --> Kerio
user2<_at_>domain.com --> MX mailserver
user3<_at_>domain.com --> MX mailserver
person1<_at_>otherdomain.com --> Kerio
person2<_at_>otherdomain.com --> MX mailserver
person3<_at_>otherdomain.com --> MX mailserver
and so on.
I can configure IMAP post boxes on the MX mailserver and mail forwarders to other mail adresses.
With my existing Exchange mailbox, it is possible to do the following:
On MX Mailserver:
firstname.lastname@example.org -> mailadress<_at_>exchangeprovider.com
On Exchange Server:
Mailbox for mailadress<_at_>exchangeprovider.com
With reply adress: realname<_at_>domain.com
That way, the "secret mailadress" mailadress<_at_>exchangeprovider.com was shown nowhere and it was possible to have the MX records pointing to another mail server with other accounts on domain.com.
I would have such a "secret" domain for a similar setup with Kerio, I however have not yet figured out how to do it.
Do you have some hints for that?
