Recipient Policies question


I would like to understand what does the "E-Mail Addresses (Policy) mean. Under Recipient Policies in my Exchange Organization there are 17 different Recipient Policies and 1 default Policy. When I right click on a domain in the "recipient policies" and choose "E-Mail Addresses (Policy)" I see under "Generation Rules"
18 different addresses. Under type some domains are enable by being checked and others are not.
My question is:
1) By checking them what does that mean?
2)By unchecking them what does that mean?

The Recipient Policies in Exchange Server control what email domains Exchange can receive and process email for. It also handles the automatic generation of email addresses onto users - that is, whenever a new user, contact or mail-enabled group is created, Exchange uses the Recipient Policies to determine what email address(es) that new user should be given.

1. By checking a policy, this means that when a user is created, that email address will be automatically added to the user.
2. By unchecking a policy, this means that Exchange can handle mail for that email domain, BUT Exchange will not automatically add the address to any new users (it must be done manually - ideal for when you have a domain where you only need one or two email addresses from it).

Remember Recipient Policies are processed based on the rules on the first tab in their Properties.

Basicall, if you have 18 different addy's...then when you create a new user w/mailbox, it will assign them each of those 18 addresses.  
If they are checked, then you can send to that address because the user will have it attached to them.
If you uncheck....the user will not have that address available.

As a clarification, policies are applied in preferential order, from top down as you view them in System Manager. Exchange will process each policy, trying to match the user to the filter on the first tab. If a match is found, Exchange stops processing further policies, and applies the email addresses it finds checked in the policy where it has stopped.

In this example, if there are indeed 18 separate policy objects within the 'Recipient Policy' container in ESM, the users will ONLY receive email addresses (only checked ones) from ONE of these policies, since it will stop when it evaluates one which matches.

If we are talking about a single Recipient Policy with multiple SMTP addresses listed on the Email Addresses tab, then the users will indeed receive all the 18 email addresses from this policy, provided ALL of those SMTP addresses are checked.
