Postfix to relay to Domino

Hello,
as mailserver i' m using SuSE 9.x (postfix).
Mails are being fetched by "fetchmail" several times of the day.
These  mail will be forwarded to the local user mailboxes, all right...
Now i want to use a Notes/Domino (Mail) Server, to which these (incoming) 
mails should be forwarded to.
In which way i've to configurate "postfix" to do this?

Thanks a lot
