Hello, Based on several posts in this forum I configured a new SPAM filter policy with this values: SPAM tag level = 0 SPAM tag2 level = 3 SPAM kill level = 5 SPAM dsn cutoff level = 0 SPAM quarantine cutoff level = 0 I have only two mailboxes affected by Spam, but the amount daily spam is big. Even using this configuration for the tags the daily amount of spam continue being big. Any suggestio, tip or help to try to reduce the spam? Thank you!
I am using Ubuntu 18.04, ISPConfig 3.2.6. and Apache with Amavis. The configuration that I shared is from the Amavis tab from the Spamfilter policy section. The tab of Rspamd has the defualt configuration.
You should consider switching your system to the more modern Spam filter rspamd, which has been used by ISPConfig as a default for several years now: https://www.howtoforge.com/replacing-amavisd-with-rspamd-in-ispconfig/ And in general, you should consider updating your OS, you are running with 6 year old software versions now.
Thank you for the information. Once I replaced Amavis how I should proceed to set the spamfilter configuration of rspamd?
It might be that your old spam scores are too low then, as Rspamd is much more effective than Amavis/Spamassassin. For E.g., a spam tag level 0 (which basically means the email is not spam, but you tag it as spam nonetheless) will likely filter out a lot of legit emails and will cause the Bayes filter to learn wrong things.
