New MailScanner installation problems

[List Account]

Hello all,

I just got my MailScanner system up and running, and it is routing mail, but 
I'm having a few issues.

#1 - spam messages are disappearing.  I have the rule for spam and 
high-score spam set to forward the mail to spam inbox, then delete the 
message.  The messages aren't always being delivered to the original address 
or the spam address.  I've gotten about 20 emails in the spam mailbox, but I 
would usually see hundreds in this ammount of time.

#2 - Spam rules seem to be pretty lenient with some messages, especially 
ones containing explicit language, as long as there's not too much of it.  
I've seen the documentation about helping the MailScanner learn from 
messages, but unfortunately we forward the mail along to Exchange.  Is there 
a way to teach MailScanner using Exchange?

Thanks in advance.
