I've used your script and it works great. I don't use it to do an automatic update, but use it to debug. For those that don't know, the blacklists use a modified DNS query. When you check them they send back a response in the 127.0.0.? range. The value determines what reject reason. If for some reason they are unreachable or overloaded your server will slow down. The more places you check the more likely you will get a slowdown. I check my smtp logs to see who is giving me responses. If I'm not seeing an rbl giving me anything I pull them. This link: http://www.kloth.net/services/dnsbl.php is a great tool for checking out rbls. I spent some time checking ips of each spam that made it through seeing if any rbl got a hit on the ip. Pretty nifty site. --------------------------------------------------------------------- QmailToaster hosted by: VR Hosted <http://www.vr.org> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
