First off, I'm very happy with SpamFilter running on Windows 2003 Server.  Just started playing with the new beta build (256) in order to see how effective the Bayesian filtering is going to be for me.  SPAM has been increasing lately.

Here are a couple of usuability requests:

1.  Need a better way to select ALL quarantined emails at once.  CTRL-A or something, if not the ability to page up/down while holding the SHIFT key.   I keep a large block of quarantines around for various reasons.

2.  When installing an upgrade, it doesn't remember or detect the folder that is currently being used.  This should be easy enough to read from the Registry.

3.  It would be nice to be able to clear the usage stats without restarting the service.  Yeah, it's not that big of a deal to uncheck the "Remember" setting, run a STOP/START at the command line, then enable the "Remember" setting again, but it shouldn't have to be that way.

4.  Is there any way to export the usage stats before you clear them?

5.  When you select a message in the Quarantine area, and then act on it (either Delete or Deliver), can the list be maintained minus the items in question without having the lists sorted?
