Unresolved Recipients like feature in EXIM

Hello,

There is a feature in Exchange to forward unresolved recipients for a domain to a certain server. I need to know if there's a way to accomplish this in Exim also.

What I have is a SBS 2003 server that is expected to reach past 75 user limit, because they're going to need hundreds of mailboxes for their domain.

What I envisioned was spinning up a VPS Linux server through HOSTGATOR, and creating POP mailboxes for all of the people who need an email address for this particular domain, but do not need full blown Exchange features.

What will happen is email bound for the domain in question will be filtered for spam via  third party, delivered to the Exchange server, and for any mailbox that does not exist for that particular domain (unresolved recipients), will be forwarded onto the POP server.

This, I have set up successfully.

What I need is to know how to do the same thing in EXIM so that people sending "internal" email on the POP server have a way to reach those mailboxes that do exist in Exchange.

I know I could set up some subdomains and do some forwarding, but the path of least resistance for me right now would be have some sort of "unresolved recipients" like feature in Exim.

There's potentially going to be hundreds of POP mailboxes, but really only 10 people who need full blown Exchange.

To forward unresolved recipients to another server in exchange 2003 go to Exchange system manager / admin groups / first admin group / servers / server name / protocols / smtp / default smtp vs - right click / properties and go the messages tab. Under forward all mail with unresolved recipients to host , enter the host or ip of your exim box...... However you do not need to do this... If it's just pop3 or imap you want exchange does this for you as well.

Hi, You can use a router on the server (after all other routers):

smarthost_route:
driver = manualroute
transport = remote_smtp
route_list = * smarthost.domain.tld
