Running two email server at once. is it possible?

[quacka]

I already have a redhat 9 server which host other services beside my emails using postfix. I have just setup another server and have Scalix running fine on it.

I don't have the time resource to replace the old redhat server yet. My question is if I want a selected number of users from the redhat machine to use the scalix server as their primary email server, how would i transfer these users emails over and retain their original email addresses?

How are your users accessing their mail on the redhat server? IMAP? You could migrate messages using an imap client. Or search on imapsync and you will find several posts with suggestions.

mainly pop3
but imap is enabled if they wish to use it but no one use it though
