Pts a lot of letters poured into the mailboxes. How to train SA correctly?

Answer 1

Understand why SA gives such low ratings.
Think about what might be worth changing them (assessments), and supplementing the rules themselves.
If spam is Russian - download Russian databases for SA.
If you can't find a solution, try pdd.yandex.ru, GApps or commercial anti-spam.
Well, it is very important when training that SA is trained on pure spam / ham databases and the number of letters there and there is comparable. That is, you need to know that these users are precisely monitoring the mailbox - they do not leave spam in the inbox and do not delete it, but carefully transfer it to the spam folder.
if you train on a user whose folders are polluted with spam, there will be more harm than good.
It is also worth remembering that many personal antiviruses include antispam modules with good functionality - also a possible solution.
