27 | 27 | '''Don't use the BLACKLIST or BLACKLIST_URI rulesets'''--they take up a huge amount of memory, and they're practically obsolete now that the SA blacklist has been moved to a SURBL lookup. The only circumstance I can think of for using ruleset-based (i.e. static) blacklists/whitelists is when you're not doing any network tests at all--no DNSBL lookups, no SPF, no !DomainKeys, no Razor/Pyzor/DCC/!SpamCop. Doing it that way saves you from network delays (latency), but of course deprives you of many very useful sources of information. A static whitelist/blacklist file can be useful in that scenario, provided you keep it up to date. |
