Anyone using the above? I notice that their product line had been discontinued. Anyone knows of any free alternatives to these?

Boon, this is why they discontinued it:

The same thing applies with the mail option, they made performing mail functions much better in .NET and very easy to implement.

Basically they just were getting the business for the products anymore.

We still use them for a couple of features (but they are just our own features). We also have Jmail and then check out Persits Software (http://www.persits.com/)
