The PIM portion of Intellect is quite good. I have used its predecessor (Time & Chaos) for a long time. The email client is flat out not safe to use if you are interested in reducing spam. Amazingly, it lacks the ability to block images in email. This makes you a VERY easy target for spammers in that as soon as you open the email, the spammer will know it because the image has to be retrieved from the spammer's web site. It's called a "web bug" or "beacon". Very easy to implement if you are a spammer.

Even the Mozilla Thunderbird email client software (which is FREE) allows you to block images in your email if you want to. Hard to believe Intellect does not.
