Spamassassin spamd basic configuration
I am running suse openexchange which uses spamassassin spamd version 2.6.3.
spamd is started with the options '-d -c -a -L -u nobody'.
spamassassic configuration file contains :-
# rewrite the Subject: line with ****SPAM**** .* if set to 1 (default=1)
rewrite_subject 0
# report briefly, recommended for report_header==1 (default=0)
use_terse_report 1
Currently spamassassin is only detecting about 30% of spam which is quite poor.
Openexchange does have some strange defaults in some places and I am questioning the use of the '-L' parameter which disables network based checks.
I have looked in /usr/share/smapassassin at the 20_dnsbl_tests.cf and 50_scores.cf files.
1) Spamassassin checks some RBL lists and the -L parameter will effectivly disable this?
2) I would imaging that enabling these checks will make quite a significant difference?
We have an 1024/256 ADSL line and get approx 1500 emails a day (just over 1 per minute).
The mail server runs its own DNS with no forwarders defined.
3) Will there be a lot of additional load on the ADSL with these additinal checks which I believe are normally DNS based?

Who is Participating?
Thanks. I have the spam filtering in amavis turned off as I am using the existing postgres configuration to send the emails onto spamd after they have been virus checked.
I'll have a look at Razor, Pyzor and DCC

2) Not necessarily... It ups the chance that spam will be detected, yes... But for me the real "clincher" has been the addition of DCC, Pyzor and Razor in addition to spamassassin (and some whitelisting:-)... Not sure how to enable these for amavisd-new though.
3) Well, extra RBL checks would (as you assume) mean some added load... But not that much really. Razor, Pyzor and DCC are even less, so these I'd really recommend... Let's see if I can find some links... http://razor.sf.net is Razor, http://pyzor.sf.net is Pyzor and http://www.rhyolite.com/anti-spam/dcc/ is DCC...
