best way to redirect mail coming to our domain to external smtp email addresses. EX2000
Posted on 2005-04-06
We just registered a new domain name. I added the new namespace to the default recipeient policy. That handles all local users.
However we have branches that have their own mail hosted through 3rd partys.
We have a single exchange server.
My ideas so far:
1)configure my anti spam software (proxys all smtp before it hits exchange box) to forward user@domain to user@remotedomain. I would have to manually key in each user (only like 40)
-Pros Keeps exchange server out of the process., do not have to create exchange contacts or mailboxes, cleaner. Mail apperas at remote host still showing original email address sent to
-cons internal users bounce mail as our ex server thinks it handles that domain namespace. I can forward all unknown users to my anti spam server, which works, but any mail coming in to a incorrect address loops between the two servers then.
2) create exchange contacts and set smtp address to current remote address
-pros works, and dont have to forward unknown receipients to spam server hence removing loop problem.
-cons have to key in 40 some temporary contacts, mail appears to be sent to the remote smtp address when the receipient recives it,
Thats what I have so far. Maybe there is a way to forward only unknown receipients to our spam server if they are part of our name space?
Ideas suggestions? maybe both my ideas suck.
Its a temporary solution. In about a year I hope to have all the remote networks part of the same exchange organization.
