You want your Exchange 2007 server to accept all the emails and then forward the required ones on to your notes server? Is that correct?

If so you need to setup your exchange 2007 server to relay to your notes server.  I have written an article here on how to setup the different types of relay:

yes that is correct, any email that is not for/from should be passed on to the Lotus Domino 6.5 server.
Glen KnightCommented:
Then you need to setup an external relay as per my article.

If there will be contacts on both systems then it's an internal relay you need to setup.

oh ok, then i suppose the internal relay is the way to go since Exchange Server is the main contact point which also redirects all of the email into Lotus Domino server.
Glen KnightCommented:
If there will be co facts on the exchange server from the domain controlled by the lotus system then yes.

If there will not be mailboxes from the other domain then use the external relay.

Thanks for your reply, basically what i want is that Lotus Domino Server handles the custom email address mailbox * (Other than of course the mailbox is in Lotus Notes itself not in the Exchange Server.
Therefore i must use the External relay (due to the mailbox is in Lotus Domino with *

DNS entry on the ISP side (add MX records of into the same external/public IP of the Exchange Server).
DNS entry on the local domain side  (add MX records of into the same internal IP of the Exchange Server).

Glen KnightCommented:
That sounds great.
Do you need anything further?
jjozAuthor Commented:
all good mate :-)

thanks for the info. I shall post another topic if i need more help.

Instead of, you could use, but always keep both (mail) domains separated.
jjozAuthor Commented:
Hi sjef_bosman,

Yes, it will be separated as the mailbox in the Lotus Domino is uniquely named.

Thanks for your reply :-)
Glen KnightCommented:
To be honest it makes no difference what domain is used, the process is exactly the same.
jjozAuthor Commented:
yes that does make sense and easy to understand:

Within Lotus i should configure a "smarthost" or "next hop" to send all mail to the SMTP server on the Exchange host.

Within Exchange, I can make it authoritative for the domain, and then add a external relay.
