I had a similar setup until recently, and like you I've been seeing spam getting through more and more despite regular running of sa-update, most of it botnet sourced. I've pretty much eliminated it now by a combination of installing dcc and razor plugins to spamassassin (reduced the spam getting through by 70% or so) and adding a backup MX with a free service that only accepts messages to relay when the primary is down (it's amazing how much spam stopped coming in when I did that). -- Steve O'Hara-Smith <steve@sohara.org>
