In the following tutorial we are going to cover the procedure of installing and integrating SpamAssassin with Exim on a CentOS 7 Linux VPS. Once the set-up is completed, SpamAssassin will be able to scan and mark the emails detected as SPAM.
What is SpamAssassin?
It is a software program released under the Apache License 2.0 used for e-mail spam filtering based on content-matching rules. It is a very intelligent email filter which uses a diverse range of tests to identify unsolicited bulk email and apply the tests to email headers and content to classify email using advanced statistical methods.
