I admin a very small network with 7 users. Email accounts for four of the users have been around for several years. Email was hopeless because of the endless amount of incomming spam. Users refused to change their email addresses. I signed up for Netriplex Antispam service for $19.99/mo, The service service blocks between 3,500-4,000 spam emails everyday before they even reach my server. The accuracy of their spam filer is amazing. I have been using the service for 6 months and can only count a total of 5 legitimate emails that were blocked from my inbox during that period. All users realized it was a godsend after adding the service, as they open up their inboxes to only see work related emails and nothing else.
I have fine turned the service a little at a time and now it is nearly perfect. Truely, 98.5% of all email received is spam. I think it is definety worth the $20/month to just capture that 1.5% and leave the rest behind.
