Quick post. For the past seven or eight years we've been using Cyren/Commtouch for a "premium" spam filtering add-in. It used to work great but I've noticed (and my customers too) that over time more and more spam was getting through that was so obviously spam, porn spam specifically, that a few customers were getting fed up and ready to jump ship. So, upon my annual renewal I switched to Message Sniffer and the difference has been profound. It does a substantially better job and blocking and identifying spam and spear phish type email. Can't be happier. I just don't know what happened with Cyren as it used to work very well.

So, although this is posted as a "problem" it's really just a very brief review and testimonial for Message Sniffer.
