OK,

Lets say for instance, you have webmaster@domain1.com on 1 server and webmaster@domain2.com on another server.  You would go into ESM, Recipients, Recipient Policies, Action, New, Recipient Policy.  Choose e-mail addresses if you get the property page dialog box.  On the general tab you must specify an LDAP filter. Exchange makes this easy for you (unless you want a more complicated filter, and will the therefore have to learn more about ldap queries), by prviding you with a nice search facility.  So, hit Modify... Take the ticks out all the boxes except the top one 'Users with Exchange mailbox', go to the storage tab, select mailboxes on this server, click browse, find you server and select it.  Hit find and it will then show you all the objects that Exchange will apply that recipient policy to.  Click OK, and the LDAP filter is written for you as if by magic.

Now, goto the Email Addresses (policy) tab.  There may be more in here then you want, so deselect the one you don't want.  To add the new domain1.com to the users on this server, you click on new, choose SMTP address, and then type @domain1.com in the address field, click OK.  You may need to put a tick in the box to select it, then apply it.  This should then give all your users on the server you selected alias@domain1.com.  If you wanted firstname.lastname@domain1.com you could have put %g.%s@domain1.com as the address in the smtp address dialog box.

Once you have added the domain as part of a recipient policy you can then set custom mail addresses for your users, using the same domain suffix.  For instance, a user called Bob Smith, would automatically have the mail address bob.smith@domain1.com and bsmith@domain1.com, but you may want him to have webmaster@domain1.com.  Because you have defined the domain in the recipient policy, you could now simply add webmaster@domain1.com to the users smtp proxy addresses in active directory users and computers.

I hope that was of enough detail for you.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

You will have to configure recipient policies by server or administrative group as far as I'm aware.  You can specify the domain suffix to apply to a group of users instead of all your users.

It was only an example,

There are many ways you can achieve what you want, but it all depends on how you want to do it.

Again, for instance, you could have the department field filled in one set of users with IT and the other with finance.  If you wanted the domain itgroup.com applying to one and financegroup.com applying to the other, you could create a filter that was only applied to users with those values in the departement field.

To do this you'd follow the steps I described above, but instead of applying a storage filter, you'd go to the advanced tab, choose field > user > department, Condition, Is (exactly), Value, department name as above.

So maybe you don't want to do it on department, but that should be enough for you to go on, to create your own filter that works for you.
