Only difference with my 'spamassassin --lint -D' output I saw was that after the line 'uridnsbl: domains to query' I have a block of 14 lines with 'dns: checking RBL sbl-xbl.etcetera' that you don't have. Probably not important. And I can't see your SARE-rules getting loaded, in my output I see SARE being loaded after the line 'config: using "/<dir>" for site rules dir'. The v310.pre and init.pre are the same as mine.
Maybe (like already suggested) the user that starts spamassassin could be checked for having a user_prefs file, or for having permission troubles. Also with 'cat mail | spamassassin -D' you should be able to see if that specific mail is checked against DCC and Razor. Again, best to check that is with the same user that executes spamassassin. You could also sniff on ports tcp/2703 (razor) and udp/6277 (dcc). Regards Menno
