Messaging Gateway

I have an Exchange distribution group that is being spammed with LinkedIn invitations. I have users who have valid reasons for accessing LinkedIn, so I can't just add the domain to my local Bad Senders group. And because the target address is for a disto group, I can't log in as a user and add the domain to a user-specifc Bad Senders group. What I need is a way to say, "If sender is linkedin.com and recipient is distro group address delete". Is SMG capable of applying this kind of logic? If so, how is it done?

TIA for any info,

Michael

You most likely have distribution list expansion on, which means the SMG will split the emails out by each member of the DL before any analysis and processes each message againts policies separately. You can turn that feature off in Administration -> Directory Integration.

谢谢感谢你们的建议好多其实我都不懂。其实登陆网站主要是为了安全。也不知道这样对不对
