Creating a group in AD to 'whitelist' message restrictions on outside senders
Posted on 2009-04-15
We've been receiving a large amount of spam to a particular distlist on our domain (firstname.lastname@example.org), and I want this distlist to only accept emails from domain accounts and a handful of external addresses (mainly our board of directors and email newsletters).
I've set this up in AD under message restrictions to only accept messages from internal staff and have manually added the external email addresses. This setup works fine, but I'm wondering whether I can add all of the 'whitelisted' email addresses as contacts to a group and then only add the group to the exception list. The reason being is that the email addresses are likely to change from time to time and I'd rather manage them in AD rather than have to update the exception list each time.
