I've always used the defaults, and havn't had any problems with them, except 
for when the spammers change their tactics, and I start getting a few in the 
unsure box again. Another training session keeps the unsure box clean again 
for a while though.

I suppose the main reason that I've kept the defaults, is that I don't want to 
risk any genuine mail ending up in the trash. Saying that though, as I've 
said I don't send the spam directly to the trash, but to my spamcheck folder, 
where I can quickly flick through it, to make sure that no ham has been sent 
there. I must say though that using the defaults, I've never had any ham sent 
to this folder. Of course changing the defaults may result in some ham being 
wrongly identified as spam, and being sent to the trash, or in my case to the 
spamcheck box.

I'm happy to use the defaults. The few ham, and spam that turn up in the 
unsure box are not a problem, and can be easily dealt with, with another 
training session.

Nigel.
