Spam filters in the form of table lookups and dnsbl queries. I'm currently processing 12,581 CIDRs 1,568 regular expressions (PCRE) 5 dnsbl lookups per each inbound connection (assuming no hits). Obviously a hit in a table early on in the processing order is going to cut the time down. I'm just wondering how much time is being consumed by processing all of these and the lookup delays to the dnsbl servers. Is it so small it's irrelevant, or is it large enough it could become an issue as I add more tables/entries and/or dnsbls, and inbound mail volume increases? Say I add another 20k CIDR or 1,500 more PCRE entries? FYI this is an old dual CPU 500 MHz 32bit x86 machine. Now you may understand my concern about running large numbers of PCREs and CIDRs per connection. Even with these old CPUs, processing these tables may be a piece of cake, I simply don't know. That's why I'm asking. It may be that all of this is a total non issue, and if so, I'd like to know that. Thanks. -- Stan
