Spamassassin seems to have become more-or-less non-functional in use with KMail on my server. It appears to be running OK, but only catches about 20% of my spam. I wonder if others have experienced this decline? I suspect that sa-learn is not performing properly. (I run sa-learn nightly on my spam, which is saved in ~/Maildir/.Spam/cur/ , through the default spamassassin installation.) Eg I receive more or less identical spam many times without it being caught. Also, about 35% of the spam that gets through is in foreign languates - Russian, Chinese, Arabic and Turkish - and it would help if I could get rid of this. I read up about catching such email in spamassassin, but did not understand exactly what changes are required. One difficultly I have is that there seem many places where one can make changes in spamassassin settings. Am I right in thinking that all such changes can be made in .spamassassin/user_prefs ? What should I put in this file to change the score for eg 3.5 BAYES_99 BODY: Bayes spam probability is 99 to 100% Any advice or suggestions gratefully received. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College Dublin
