We’re using MailMarshal on our Exchange environment for incoming messages only. We’re pretty happy with it, but we’re getting close to the time to review our options as well. I have sat through a couple of demos on Ironport and it looks good too. A related question – anyone filtering outbound mail, but also allowing constituents to forward their mail to personal addresses? I’d like to move us to scanning outbound messages to decrease our likelihood of being black/grey listed and as another layer of defense against phishing schemes. However, my guys are having trouble working out the issues with notifying someone that an outgoing message was blocked when they’re having their mail forwarded. We’re left with not notifying them or creating possible mail loops.

We've been using Ironport over one year, pretty happy about it, and we are filtering both in/out-bound email messages (~10 millions every day), whereas 97% of incoming messages are dropped by Ironport which is a huge relief to the inhouse email servers. feel free to contact me off-line if you have any questions.

Date: Wed, 26 Aug 2009 14:10:18 -0400 Hello, everyone. I hope you're enjoying a calm and peaceful beginning to another semester. Though this is a recurring question, I haven't seen it posed on this list in a while. What is everyone using for anti-spam/anti-virus filtering on email these days? We're moving away from our current appliance, and exploring our options for the first time in a few years. Feel free to email me off-list. If people are interested, I'd be happy to summarize numbers and comments. Let me know. --Matt
