Exim doesn't support tightly-coupled clusters. This is a weakness in the implementation of the hints DBs, and fixing it was outside the scope of the ratelimit project. There are other things that would benefit from better hints DBs: the current implementation is a major bottleneck for high capacity servers, so there's scope for improved performance; sharing the hints DBs will reduce duplicated work across a cluster (retrys, callouts, etc.); greylisting would be much better if implemented cluster-wide rathe than per-machine. Perhaps one day someone will tackle it :-) Tony. -- <[EMAIL PROTECTED]> <[EMAIL PROTECTED]> http://dotat.at/ ${sg{\N${sg{\ N\}{([^N]*)(.)(.)(.*)}{\$1\$3\$2\$1\$3\n\$2\$3\$4\$3\n\$3\$2\$4}}\ \N}{([^N]*)(.)(.)(.*)}{\$1\$3\$2\$1\$3\n\$2\$3\$4\$3\n\$3\$2\$4}} -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
