I've seen some mention of access control for distribution lists.
I've seen some mentions of this in the forums for lists like
all@server.com or
staff@server.com. The goal of these lists is to be able to send email to a whole large group of people. I realize that's obvious. The problem is that they can also become a very nice source for spam.
There's a "Hide in GAL" option which is useful for the casual browser. There's also the "Can receive mail" option which I assume is an enabled option. However, these don't protect against malicious intent.
Example: Somebody sends an email to the staff. Staff forwards this message to a concerned customer. Customer shows an involved customer of theirs. Customer is upset because of whatever might be going on and mail bombs the list creating a huge multiplication of emails. Not only that, but it's the Zimbra server that's doing all of the work of multiplying the emails.
I know this feature has been requested a few times and is a only going to be implemented if enough request is made.
I saw a reference to this link (
http://wiki.zimbra.com/index.php?tit...tfixRecipients) which didn't seem too horrible, but it would be nice if there could be a GUI option and possibly sender verification.
Is there any way to make this post sticky and let any curious users express their interest? If I recall correctly, there's also a bug tracking system that users can vote interest in. Is there any way to move this into that and also leave a sticky so people can have a reference?
Yup - I have a feeling mmorse will be the first to respond to this.

Hi Mike.
