How do I
configure some Exchange recipients to
have different e-mail addresses in
Exchange 2000/2003?
Exchange 2000/2003 will
automatically configure e-mail addresses
for your recipients, based on the name
of your Active Directory domain.
For example, if you have
an AD domain called TEST.HOME and you've
installed Exchange 2000/2003 on it, each
and every mailbox enabled user, mail
enabled user, mail enabled group and
mail enabled contact you have will
automatically have an e-mail address of
ALIAS@TEST.HOME.
However sometimes we
would like to configure other e-mail
addresses for our recipients, for
domains other than our own, internal
domain name. Basically, Exchange can
handle hundreds of mail domains without
any problem (up to about 1000 domains),
so performance is usually not an issue.
For example, some users
might require additional e-mail
addresses that will better reflect their
position or role in the company (such as
"support" or similar). You might also
need to configure totally different
e-mail addresses for other users, such
as where these users work for a
different subsidiary or even when you're
using one server to host multiple
companies and therefore require
different domain names for different
recipients.
In all of the above
examples you'll need to configure
Exchange to use new (or modified)
Recipient Policies to reflect the change
in the e-mail domain names. However,
unlike the case described in my
Configure Exchange 2000/2003 to Receive
E-Mail for other Domains article, you
cannot modify the Default Recipient
Policy, because that will cause all your
recipients to receive the new e-mail
address. You will need to configure a
new Recipient Policy and have it filter
out the recipients it will effect.
-
Open the Exchange
System Manager.
-
Navigate to the
Recipients folder, expand it and go
to Recipient Policies. Right-click
Recipient Policies and choose New >
Recipient Policy.
Note:
You can also modify the existing
Recipient Policy, but that will not
allow you to choose specific users
or recipients on whom you'd like the
new policy to apply. This is because
the Default Recipient Policy will
not allow you to modify the LDAP
search filter, and it will always
apply to all the Exchange recipients
in your organization. Read the
Configure Exchange 2000/2003 to
Receive E-Mail for other Domains
article for more info.
-
In the Properties
window of the new Recipient Policy,
give the new policy an appropriate
name, and click on the E-Mail
Address Policy tab.
-
On the E-Mail Address
Policy tab you can add all sorts of
e-mail addresses, but the most
common one is SMTP of course. Click
New, choose SMTP and then configure
your Internet E-Mail Domain name
(the one you plan to add to all your
Exchange recipients - users, groups,
contacts and Public Folders).
Remember to add a "@" sign before
the new domain name. You can also
select the new e-mail address to be
the primary address (i.e. in bold,
and it will be used as the e-mail
address to where the replies to
messages sent by your users will be
sent). When you're done click Ok.
-
Go back to the
General tab and click on the Modify
button to create the correct LDAP
search filter.
In the Find window
select the appropriate search
filter. You can use some of the
built-in attributes or create your
own set of attribute-based query.
For example, you can
choose only recipients that have
mailboxes on a particular server:
Or you can only
select user-type recipients that are
located within a specific store on a
specific server and so on.
Important Note:
You are not required to create a
filter! You can actually leave the
filter option empty, and later
manually add the required e-mail
address to any user you want by
using the AD Users and Computers
snap-in. For example, if you only
had a couple of users that need to
accept email for a secondary domain,
then you could simply create a new
recipient policy with a blank filter
and manually put the addresses on
the two accounts.
In this example I've
used a query based upon the
Department attribute of a user. Read
my LDAP Search Samples for Windows
Server 2003 and Exchange 2000/2003
article for more info on the
subject.
When you're done with
the search filter click Ok. You can
also click on the Find button and
see the results your filter gave
you. These will receive the new
Recipient Policy's settings, and if
you're satisfied with what you saw -
click Ok.
Read my Configure
Specific E-Mail Addresses for
Specific Exchange 2000/2003 Users
article for more info on this issue.
-
Read the Exchange
System Manager message that pops out
and click Ok. Basically, this
message tells you that if you plan
to make changes to this filter you
should then run the Apply Policy Now
option.
.
-
After you've set your
new policy, you will now need to
apply it. Right-click it and select
Apply this Policy Now.
-
In order to make
things happen faster, you'll want to
re-run the Recipient Update Service
- or RUS - (both of them in most
cases, all of them in case you have
a few AD domains). Go to the
Recipient Update Service folder and
in the right pane right-click all
the instances of the RUS you see,
and select Update Now.
-
In order to test the
success of the new Recipient Policy,
go to one of the recipients that
should have been affected by the new
policy and see if the new e-mail
address is listed in the recipient's
properties.
Done! In cases where the
new e-mail address we've just configured
is a sub-domain of your current existing
domain you'll need to contact your ISP
or Name Server provider and ask them to
add a sub-domain to your existing
domain. |
