SA-learn on remote host

[John K Masters <johnmasters@oxtedonline.net>]

I am gradually implementing a mail system where I have a mail-server on
host1 running Postfix/Courier/Procmail/spamc which passes all except
whitelisted mail to spamd on another server - host2. host2 simply runs
the mail through SA and passes it back to host1 from which I read on my
local box via Mutt. 

Most spam gets filtered into the .Spam folder and I have bound keys in
Mutt to move missed spam to this folder and to copy good messages to a
.Ham folder.

What I would like to do now is have a cronjob run the contents of these
two folders through SA-learn and then delete them. ATM I am stumped as
to how to go about this. Any pointers very welcome.

Regards, John
