Rspamd communigate pro2/3/2024 ![]() If you don’t want to handle those pseudo virus names like everything else you could use patterns to setĪ different symbol and maybe set a score or use the symbol in force_actions. When enabled, pseudo virus names (SAVDI_FILE_OVERSIZED, SAVDI_FILE_ENCRYPTED) will be set in case Sophos reports an encrypted file or if the file is bigger than maxscandata in the scanprotocol section of the SAVDI configuration file. SOPHOS_VIRUS_FAIL), making the following configuration obsolete.įrom version 1.7.2 up to 1.8.3, there are two special configuration parameters for handling SAVDI warnings/error messages in the sophos section: savdi_report_encrypted and savdi_report_oversized. Note: Since version 1.9.0, SAVDI errors will be reported in the fail symbol (e.g. A sample SAVDI configuration can be found at Rspamd uses the SSSP protocol to communicate with SAVDI. Both Sophos Anti-Virus for Linux and the Sophos SAVDI daemon need to be installed. Sophos SAVDI is a daemon that extends Sophos Anti-Virus for Linux to be reachable via TCP sockets using the generic ICAP or the Sophos-specific Sophie and SSSP protocols. # `whitelist` points to a map of signature names. # If set force this action if any virus is found (default unset: no action is forced) # multiple scanners could be checked, for each we create a configuration block with an arbitrary name Settings should be added to /etc/rspamd/local.d/nf file: # local.d/nf The options scan_text_mime or scan_image_mime can also be set to true if you want text mimes and images sent to the AV scanner.īy default, if Redis is configured globally and the antivirus option is not explicitly disabled in the Redis configuration, the results will be cached in Redis according to message checksums. This behavior can be changed by setting the scan_mime_partsoption to true, which will send all detected attachments as separate mime parts. The mime_parts_filter_ext option matches the extension of the declared filename or an archive’s file list.īy default, the complete email will be sent to the antivirus system. The latter option also works for files within an archive. The mime_parts_filter_regex option matches the content-type detected by Rspamd, or a mime part header, or the declared filename of an attachment. # Mime-Part filename extension matching (no regex) GEN2 = "application\/vnd\.openxmlformats-officedocument.*" For the fail symbol, the patterns_fail option must be used.ĬLAM_LIMITS_EXCEEDED = '^Heuristics\.Limits\.Exceeded$' įrom version 3.5, you are able to use two more types of mime part filters. In addition to the SYMBOLNAME and SYMBOLNAME_FAIL symbols, there are currently two special symbols indicating that the scanner has reported encrypted parts or parts with Office macros: SYMBOLNAME_ENCRYPTED and SYMBOLNAME_MACROįor virus, encrypted and macro symbols, patterns can be used to set a dedicated symbol for any virus name or error message. The force_actions plugin can be used to perform a soft reject if the antivirus has failed to scan the email, such as during a database reloading. CLAM_VIRUS_FAIL) will be set, with the error message as the description. In case of errors during the connection or if the antivirus reports failures, the fail symbol (e.g. If set, the reset action will be triggered. CLAM_VIRUS) will be set, with the viruses as the description. If the antivirus reports one or more viruses, the configured symbol (e.g. The configuration for an antivirus setup is accomplished by defining rules.

You can feed emails through rspamc learn_spam or rspamc learn_ham for manual spam/ham training to improve Bayes hit rate. Rspamd offers a nice way of Bayesian learning in Rspamd statistical module. At Onlime GmbH we have migrated the mail infrastructure in Dec 2019 from good old Spamassassin to Rspamd which greatly improved spam filtering.
