We are using a pair of Dual PIII 1.4ghz boxes to do this: URL:http://stats.sonic.net/public_cricket/grapher.cgi?target=%2Fservers%2Fspamcan%2Fspamcan%20aggregate%20%28sum%29;ranges=d%3Aw;view=SpamdMessages It's a bit overloaded and an additional server is really needed to provide N+1 redundancy. There is a cluster of 6 sendmail servers calling spamc as part of the local delivery process with procmail -- tagged spam is optionally rerouted to a web based graymail & SpamAssassin configurator that if it wasn't completely tied into our user management system, we'd be releasing back to the community. This isn't the fastest way in the world to do this, but it's proven to be very flexible. This represents load from ~10k users, about a 1/4 of the total load handled by our mail servers - ~1m messages a day. In order to keep performance up with all network tests enabled, each server has a local DCC and bind server which is authoritative for most of the RBLs in user. Alot of performance could be gained by disabling network tests and the AWL, etc. -- Kelsey Cummings - [EMAIL PROTECTED] sonic.net System Administrator 2260 Apollo Way 707.522.1000 (Voice) Santa Rosa, CA 95407 707.547.2199 (Fax) http://www.sonic.net/ Fingerprint = 7F 59 43 1B 44 8A 0D 57 91 08 73 73 7A 48 90 C5 ------------------------------------------------------- This sf.net email is sponsored by: With Great Power, Comes Great Responsibility Learn to use your power at OSDN's High Performance Computing Channel http://hpc.devchannel.org/ _______________________________________________ Spamassassin-talk mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/spamassassin-talk
