RE: SBS 2003 SP1 and Exchange SP2



Hi Courtney,

Thanks for posting here!

For your description, I understand that you got error " The administrative
limit for this request was exceeded." When you try to add send filters on
Exchange 2003 server.

Based on my knowledge, this is an Active Directory error caused when the
non-linked attributes stored in an Active Directory object exceeds the
limitations. A nine-byte tag for every value must be put on the database
record for that object, and database records cannot span multiple database
pages (8k). That implies a theoretical upper limit of 910 values (across
all non-linked attributes) on a single DS object. In fact, the number is
~50 lower because of fixed fields in the database record.

Due to this AD limitation of the non-linked attributes, the Turf list in
Exchange (i.e. Recipient filtering + Sender filtering + Connection
filtering) is limited to approximately 850 total entries.

For your now situation, I suggest that you refer to the following KB
article to automate the removal of all of the extra addresses.

Removing duplicate and unwanted proxy addresses in Exchange
http://support.microsoft.com/?id=318774

And there is another possible workaround, that is instead of filtering on
individual email addresses or domains, enable "filter recipients who are
not in the directory" on the Recipient Filtering. This should dramatically
reduce the amount of SPAM hitting the server. If so, you may be able be
able to remove/reduce most of the Sender Filtering which will lower the
number of non-linked attributes stored on the Message Delivery object
settings.

Hope above information helps! I am happy to be assistance of you and look
forward to your reply!

Have a nice day!

Sincerely,

Jenny Wu
