Hello,I have started using the 2007 Exchange Management Console interface to add Blocked Domains by going to Organization Configuration>Hub Transport>Anti Spam>Sender Filtering>Blocked Senders. If I try to add more tham 100 domains, I get a message that stops me and says "too many items allowed, maximum count is 100".Yet the Microsoft techNet documention shows that the limit for the Set-SenderFilterConfig -BlockedDomains parameter is 800. Does anyone know why I am being limited to 100 entries or how to increasethe paramter to 800 entries?

Hi, Please let me know whether Service Pack 1 is installed on the Exchange Server (Edge or Hub). I would like to explain thatthis issue will occur with the following attributes on the following objectsSenderFilterConfig - BlockedSenders, BlockedDomains, and BlockedDomainsAndSubdomainsIPBlockListProviderConfig - BypassedRecipientsRecipientFilterConfig - BlockedRecipientsExchange 2007 RTM is hardcoded and can only support 100 items/values on these specific settings.Mike

Service Pack 1 is not installed on our Exchange Server. So if I'm understanding correctly, installing service pack 1 will allow me to add 800 blocked domain entries?

Yes, you whould be able to add 800 blocked domain entries after updating to Exchange 2007 Service Pack 1.Mike
