SpamAssassin implements a comprehensive approach to blocking decisions: each message undergoes several checks (context analysis, DNSBL blacklists and whitelists, trainable Bayesian classifiers, signature checks, sender authentication via SPF and DKIM, etc.). After assessing the message through various methods, a certain weight coefficient is accumulated. If the computed coefficient exceeds a certain threshold \u2014 the message is blocked or marked as spam. Automatic rule update tools are supported. The package can be used on both client and server systems. SpamAssassin code is written in Perl and distributed under the Apache license.<\/p>\n<p><noindex><a rel=\"nofollow\" href=\"http:\/\/svn.apache.org\/repos\/asf\/spamassassin\/branches\/3.4\/build\/announcements\/3.4.3.txt\">Features<\/a><\/noindex> of the new release:<\/p>\n<ul>\n<li class=\"l\"> A new plugin OLEVBMacro has been added, designed to detect OLE macros and VB code within documents;\n<li class=\"l\"> Increased speed and security of scanning large emails with the body_part_scan_size and<br \/>\nrawbody_part_scan_size settings;<\/p>\n<li class=\"l\"> The message body processing rules (body) now include support for the 'nosubject' flag, which stops the search for the Subject header as part of the text in the body of the message;\n<li class=\"l\"> For security reasons, the option 'sa-update \u2014allowplugins' has been deprecated;\n<li class=\"l\"> A new keyword 'subjprefix' has been added to the settings to include a prefix in the email subject when a rule is triggered. A tag '_SUBJPREFIX_' has been added to templates that reflects the value of the 'subjprefix' setting;\n<li class=\"l\"> The DNSEval plugin has been enhanced with the rbl_headers option to specify headers that should be checked against RBL lists;\n<li class=\"l\"> A check_rbl_ns_from function has been added to verify the DNS server in the RBL list. A check_rbl_rcvd function has been added to check domains or IP addresses from all Received headers in the RBL;\n<li class=\"l\"> The check_hashbl_emails function has received options to determine which headers should be checked in RBL or ACL;\n<li class=\"l\"> A check_hashbl_bodyre function has been added to search the email body using a regular expression and verify found matches in the RBL;\n<li class=\"l\"> A check_hashbl_uris function has been added to identify URLs in the email body and verify them in the RBL;\n<li class=\"l\"> A vulnerability (CVE-2018-11805) has been addressed, allowing the execution of system commands from CF files (SpamAssassin configuration files) without reporting their execution;\n<li class=\"l\"> A vulnerability (CVE-2019-12420) has been fixed, which could be exploited to cause a denial of service when processing an email with a specially crafted Multipart section.\n<\/ul>\n<p>SpamAssassin developers have also announced the preparation of version 4.0, which will include full built-in UTF-8 processing. Publication of rules based on the SHA-1 algorithm will be discontinued on March 1, 2020, as SHA-256 and SHA-512 hash functions replace SHA-1 in the 3.4.2 release.<\/p>\n<p><noindex><a rel=\"nofollow\"
