SpamAssassin is the most popular open source spam filtering software. It has won numerous awards, and has been incorporated into many commercial filtering applications.
So it's important for law firms seeking to maximize deliverability to keep an eye on the tests used by SpamAssassin to assign scores to email messages.
At the end of January, SpamAssassin announced version 3.3.0, their first major update since 2007. The new release contains many of the already familiar tests (e.g. assigning points for use of the word "Viagra"). But there are some interesting ones - for example, you can be penalized if your email contains the following: 'Dear (something)' - so much for personalization.
Also interesting: the word "free" in the body doesn't appear to earn a penalty, unless spaced oddly (or capitalized).
