![]() SpamAssassin has several "deep scanning" and network lookup filters, that may take some time depending on the size, content, complexity and layout of a message. Or you can block them based on domain name using dns_query_restriction deny ĭns_query_restriction deny Performanceīefore reading this chapter, please familiarise yourself with the general performance guidelines. ![]() To your configuration, or disabling some of them by adding lines such as score _RCVD_IN_ZEN 0 # SpamHaus If you have a very high traffic system which is likely to be blocked by all SpamAssassin's included DNSBL lists, you can disable all of them by adding skip_rbl_checks 1 However, your system's accuracy or performance shouldn't be significantly degraded if some of those DNSBL's start blocking you. Some of them might, or might not, be free for you to use. SpamAssassin has strict policy for which DNSBL lists to include by default. If (ScanSA() >= 5) Reject("Rejected by spam filter (".$transaction.")") DNSBL usage If (ScanRPD() = 10 and ScanSA() >= 3) Reject("Rejected by spam filter (".$transaction.")") If (ScanRPD() = 50 and ScanSA() >= 2) Reject("Rejected by spam filter (".$transaction.")") if (ScanRPD() = 100) Reject("Rejected by spam filter (".$transaction.")") if (ScanSA() >= 5) Reject("Rejected by spam filter (".$transaction.")") Īnd to combine it with Cyren's RPD engine you can call on the ScanSA() function for all classifications other than "spam" (100). SpamAssassin can be invoked by using the built-in ScanSA() function in the EOD context. Score RDNS_NONE 0 # We don't do reverse lookups for performance reasons Use_bayes 0 # Faster Bayes database (lines below)īayes_path /storage/spamassassin/bayesian/bayesīayes_store_module Mail::SpamAssassin::BayesStore::SDBM ![]() Lock_method flock # Faster locking method It's possible to add your own rules on the Configuration -> Anti-spam/virus -> SpamAssassin page (the configuration key antispam_sa_config). Rules are updated through SpamAssassin's own channel. Bayesian is disabled because our standard configuration doesn't run SpamAssassin on messages with a CYREN "spam" classification.įor information on what rules are included by default, please see SpamAssassin's official default rules page. The integrated package ship's with SpamAssassin's default configuration, with the exceptions list below.
