During the last 24-48 hours, we have had an enormous increase in the amount of spam and infected emails coming through. I've already opened a case with support but I thought I'd see if anyone else is experiencing this.
During any given 24 hour period, our UTM blocks approximately 60% of the incoming mail. In these last 48 hours (up to and including right now) it's only blocking 1%-2% and end users are receiving a ton of infected emails and very obvious spam/phishing messages at their desktops.
The only change I've made in the last week or so with regards to the SMTP proxy is I've re-enabled "strict RDNS checks" (post 272496).
