Upgrading From an Older Version?

If so, please take the time to read Upgrade Notes while you're downloading.

Product Information

The core distribution consists of command line tools to perform filtering along with Mail::SpamAssassin, a set of perl modules which allow SpamAssassin to be used in a wide range of products.

System Administrators

Please create a local copy of the report_template text in a file named something like /etc/mail/spamassassin/10_local_report.cf, and modify it to provide your tech support desk's contact information, instead of the default. Otherwise your users will be confused, and some may ultimately contact the SpamAssassin development team, which is not appreciated; we cannot help them with whitelisting/blacklisting/customisation of settings at your site, after all. The default report text can be found in the file rules/10_misc.cf.

Verify the integrity of the files

All official releases of Apache SpamAssassin are signed with a GPG key. Each download link below is accompanied by links for the GPG signature and SHA-256 and SHA-512 checksums for that download file. The public GPG key to verify with can be found at SpamAssassin Release GPG Keys and also at KEYS. Instructions on how to verify the integrity of the downloaded file, as well as another copy of the signatures and checksums to compare with those in the links on this page, can be found in the 3.4.5 Release Announcement.
