Andy, I'm a DIY operation, not a sysadmin. FWIW, I don't run my email through
Spam Assassin. I haven't needed to do so yet. One rule might be to delete any
'Received from' headers which contain 'dynamic' in the domain name. I am
unsure whether SpamAssassin knows how to do this.
Consider using the Spamhaus ZEN[*] DNS blocklist as your first line of
defence. The spam you quoted would have been blocked since it's
currently listed both in the PBL and the XBL/CBL (although it was
added to the CBL on the 20th, for participating in a botnet):
http://www.spamhaus.org/query/ip/114.41.160.224
The PBL lists "dynamic" IPs and others that should not be sending e-mail.
Best wishes,
Daniel
