Hmmm. We have a 300 and the LDAP settings are configurable per domain. Perhaps the 400's "per domain" features have to do with delegated administration rather than recipient filtering? If the 300 is in the price range it might be worth a call to Barracuda. We've also had our 300 for going on 4 years, so maybe things have changed over time.

Each server is only supporting about 50 users, to get the per domain you need the 400. The cost per user is too high. I was pretty sure Brightmail could do it, but I don't buy anything from Symantec. I operate a simple policy when it comes to Symantec products - if they are installed and there is a problem, the problem is the Symantec product. In most cases, the problem goes away when the Symantec product is removed. Proofpoint - looks good as I could run it on a VM. However no pricing online, that always makes me suspicious. Pricing based on what they think you can afford. Any other suggestions? Simon.

I don't have your particular setup, but each domain is configured independently. I don't know why you wouldn't be able to point to an appropriate DC in each domain. A quick call to pre-sales support should answer the question definitively. RS From: Simon Butler [mailto:si...@sembee.co.uk] Sent: Monday, November 23, 2009 1:05 PM To: MS-Exchange Admin Issues Subject: Anti spam Appliance / Application with Multiple LDAP domain support Hello, Does anyone know of any anti spam application or appliance that has support for multiple independent LDAP lookups at the domain level? I have a client that has a single IP address, but three completely independent domains with their own Exchange servers behind it. I need to replace the current SMTP gateway with something that can do LDAP lookups for recipient validation. Mail Foundry can do it, but their European support is rather weak. Spam Titan can also do it, but the reviews aren't too great. Anyone know of any others?
