A common thing is to use procmail to make sure that SA doesn't filter 
messages over a certain size.   For example, this rule will skip anything 
over 250 K:
	:0fw
	* < 256000
	| /usr/bin/spamc
[assuming you're using spamc/spamd]

You can also give spamc a "-s" option with the size factor.  Both of these 
options are mentioned in the spamassassin documentation, FYI.

Also, regarding the external SA tests:  I have none of these enabled, not 
even the DNS tests.  It still works quite well with the static rules and 
the Bayesian filters.  I get about 75-100 spams a day and only about 2-3 
get through.  I really need to get around to enabling the external tests 
to see if I can improve that even further.

Regards,
Jeremy
