Exchange Block out non-domain recipients

[Bunbu]

Hi all,

I need to blacklist a few outgoing recipients but I don't know if this is something that can be accomplished within exchange. Some customers opt-out from our newsletter but I found out that some sales persons still have their contact information on Outlook, so when they send a mass mail the recipients are still getting messages from the company and a few of them had complained about it.

Is there an easy way to accomplish this?

Thanks before hand for reading this post.

Create any mail object (mailbox, contact, DL or PF), and assign to it the external email addresses you want to block as secondary proxies. When anyone internally attempts to send to any of these email addresses, the address will resolve to the internal object instead and deliver there. If it's a memberless DL the email will effectively blackhole.

Thanks for your reply, it makes a lot of sense what you suggest but how do I add a secondary proxy to a single contact without having to modify the recipient policies? I'm a little bit lost here.

Thanks again
