Brightmail does.
And I'm pretty sure Barracuda does as well.

Thanks, JB From: Simon Butler [mailto:si...@sembee.co.uk] Sent: Monday, November 23, 2009 10:05 AM 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?
