We have Mail Protection license on one of our UTM120s and we've been getting considerably more spam over the last 1-2 months. For the longest time it filtered out almost all the junk mail, but now I'm getting 20+ spams a day in my email box. Not sure whats going on, but it feels like the spam filters are no longer working as efficiently.
I am currently using the following RBLs in this order:
1. zen.spamhaus.org
2. bl.spamcop.net
I have the filter set to block "Confirmed Spam".
Not sure if this is the problem or if should be looking elsewhere. As I said, it worked fine for months but the last month or two has been quite ugly. For the cost of the license it should be working better of late. I get more spams than legitimate emails now. I have not made any changes to the settings in the UTM120 in months so its not because of anything I might have changed.
Thanks,
Chris
