Linux under SpamAssassin Configuration

SpamAssassin is a mail filter that is installed on a mail server host to identify junk letters. It uses a large number of preset rules to check spam, which checks the headers, texts, and messengers of all messages sent to the domain. The way he uses it is to use the scoring system, which means that it will be judged as SPAM according to the criteria we set, and if you use the mail server, we'll take a look at the SpamAssassin configuration method.
