Im looking for ideas to make my spamfilter better. I catch a lot of spam, but I am still getting some spam in my inboxes and I also have some false positive spam (mostly thats because of razor btw). Its an old domain, and some of the email addresses are "exposed", they where on websites as plain text for long time Im currently using spamassassin with razor2 and the with following plugins: Mail::SpamAssassin:lugin:: SPF Mail::SpamAssassin:lugin:: TextCat I also use in my local.cf file some manual rules and the blacklist_from and whitelist_from configs. I am also running sa-learn as a daily cron job, to make spamassassin learn the spam and the ham mails. Sa-learn has been running for almost six month now, but I can not see any good or bad effects of the sa-learn. Can I do something to make it more effective maybe? I also tried the TxRep as an AutoWhitelisting plugin and I think it would be really good but unfortunately this plugin is not so maintained, and generated a lot of errors on my server, also almost doubled my server load. (I used it with mysql database as I was told it should be faster). I would prefer a good working solution for AutoWhitelisting, so spamassassin could learn the outgoing email addresses (and servers) and therefore avoid false positive spams, but I could not find a working and effective solution. I know there are no 100% solutions but there must be always a way to make things better. Any suggestions?
