I manage several Barracuda Spam filters. When an e-mail is sent through the barracuda to somebody and it seems to have spammy charactertistics but is not clearly spam, the barracuda will place it in the user's quarantine. Once a day it sends an HTML e-mail notification of all the messages the user currently has in spam, with links to the barracuda applicance.
My question is to those of you who have a Barracuda Spam filter out there... do you make this quarantine page accessible from outside your network? So if a user clicks on the links in the e-mail from outuside of your network (such as at home) they are still able to access their quarantine?
