Is there a way to exclude emails that come from a particular member on behalf of LinkedIn? When someone signs up for LinkedIn, it grabs the email addresses from that person's address book and sends invitations to everyone in it. If that person has the email addresses for the various sections of the Nabble forum in their address book, it sends invitations to the forum.
We had this issue with Yahoogroups and were able to get LinkedIn to opt-out our Yahoogroups email address. But with Nabble, everyone had their own email address for each section of the forum and while we can opt out each email address individually once an invitation is sent, that won't stop future emails from other members going through.
So we'd rather just block any emails from LinkedIn to start with. Is there a way to do this?
