New version SpamAssassin v3.4.4. The changes from spamassassin.apache.org:

• FromNameSpoof: the default value of the fns_extrachars parameter was increased to 50.
• nosubject and maxhits tflags now work correctly with sa-compile.
• Added new subject prefix keyword. This can be used to add a prefix to an email subject if the original email matches a certain rule.
• New function Util::is_fqdn_valid() to validate the format of hostnames (DNS names) (error 7736). To check if a name contains a valid TLD, it is still necessary to additionally use RegistryBoundaries::is_domain_valid().
• New OLEVBMacro plugin to detect OLE macro in documents attached to emails. This plugin requires Archive::Zip and IO::String Perl modules to work.
• Due to the dangerous nature of the sa-update --allowplugins option, a warning is now issued that --reallyallowplugins is required to use it. This is to ensure that all legacy installations and wiki guides, etc. that still use it unnecessarily are fixed.
• The TxRep and Awl plugins have been modified to be compatible with the latest Postgresql versions. You should update your SQL database with the following command: MySQL: "ALTER TABLE txrep CHANGE count msgcount INT(11) NOT NULL DEFAULT '0';";" "ALTER TABLE awl CHANGE count msgcount INT(11) NOT NULL DEFAULT '0';";" "ALTER TABLE awl ADD last_hit timestamp NOT NULL default CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP;";" PostgreSQL: "ALTER TABLE txrep RENAME COLUMN count TO msgcount;" PostgreSQL: "ALTER TABLE txrep RENAME COLUMN count TO msgcount;" "ALTER TABLE awl RENAME COLUMN count TO msgcount;" "ALTER TABLE awl ADD last_hit timestamp NOT NULL default CURRENT_TIMESTAMP;".
• body_part_scan_size 50000, rawbody_part_scan_size 500000 default values added (error 6582). These allow safer and faster scanning of large emails.
• All pseudo-headers now return decoded headers, so their usage is consistent with simple header matching (:raw returns undecoded and folded as before).
• RegistryBoundaries did not load 20_aux_tlds.cf correctly in older versions. The old hardcoded list is now removed and RB prints "no tlds defined, need to run sa-update" unless it can find a list from the configuration files.
• Deprecated functions: Parser::is_delimited_regexp_valid(), Parser::is_regexp_valid(), Util::regexp_remove_delimiters(), Use::make_qr(). These are all combined into the new Util::compile_regexp() function.
• DNSEval: adds "check_rbl_headers" to check specific headers in RBL.
• DNSEval: adds "check_rbl_ns_from" to check against an RBL for DNS servers.
• HashBL: adds check_hashbl_bodyre, check_hashbl_emails, check_hashbl_uris, hashbl_ignore.
• ASN: support IPv6 with asn_lookup_ipv6 (bug 7211).
• sa-update: new --httputil option to force the download program used.
• Added rules_matching() expression to meta rules.
• Added tflags domains_only/ips_only to DNSEval.pm functions.
• RelayCountry: added new metadata: X-Spam-Country-External (_RELAYCOUNTRYEXT_), X-Spam-Country-Auth (_RELAYCOUNTRYAUTH_), X-Spam-Country-All (_RELAYCOUNTRYAUTH_) - New tflag "nosubject" for "body" rules to stop matching the subject that is part of the body text.

09/03/2021

• New Apache SpamAssassin Version 3.4.2
• Sa-update now uses SHA-256 and SHA-512 hashing for verification.
• Corrupted HTML-Emails do not crash the service anymore.
• Several new Plugins, Mail::SpamAssassin::Plugin::HashBL and Mail::SpamAssassin::Plugin::Phishing.
• More security issues have been fixed.
