A couple weeks ago, one of our customers noticed that they were having a lot more SPAM coming through the Untangle. Normally they would get 5 or so a week that would sneak through, but last weekend, one of the users had 38 that ended up in her junk mail box and 7 more in her inbox.
I have the SPAM filter on the second most aggressive setting and that the emails that do make it through have a low enough SPAM score that they would have made it through anyway.
Any reason why this would start happening? More than one customer is having this issue and all are using their own Exchange Server.
