I'm just curious what people are using for anti-spam solutions other
than M+Guardian, GWAVA, or Postini. Do your solutions allow users to
easily report spam that makes it into their inbox? Handle their own
personal white/blacklists?

We used to use M+Guardian, but had reliability issues. We switched to
GWAVA and unfortunately have had some reliability issues, though not as
many, but a lot of the end-user management (white/blacklists, reporting
spam, etc) is missing. Don't want to use anything hosted like Postini.

I'd love to still use a software-based solution so that I can
virtualize it, but at this point I'm not ruling out appliances such as
Barracuda and IronPort.

Does this washcloth smell like chloroform?
