Hm, it really is that easy. I've got used to this culture that complex packages won't do anything useful until configured so that's why I was reluctant to install bind, thinking it would take up a lot of time and effort. Anyway, it's helped. It seems to take about 5 seconds per message instead

RE: DNS timeout problem

2007-07-06 Thread James D. Rallo
Are you running a local dns caching server? Do manual queries to rbls take a long time? (Hint: Don't run the query again, as it may be cached up stream and may give a fast result.) You didn't attach your conf, but you may also want to set dns_available yes in your local.cf to save the dns check.
