We are planning a rollout that should be able to handle 500K message per day on a server. Dual P3 1.2 GHz, 4GB RAM, 4x36 GB drives for spool storage. The Mimedefang work directory will be a 250MB ram disk. >From my experience on a couple of smaller scale MD servers (Dual P3 800Mhz w/ 512MB of RAM), the important thing is enough having enough RAM. 1) Having the MD work directory in RAM. Saves tons on disk I/O 2) Having enough RAM to enough MD slaves to handle the mail load. Moving the MD directory from hard disk to a RAM drive was the biggest boost to throughput. The smaller servers went from straining 1.5 msg/second to being able to handle upwards of 3 msg/second. And there are servers with 512MB of RAM. And they handle roughly 20,000 incoming e-mail a day. They operating at an load average of .7 . -- Stephen L Johnson [EMAIL PROTECTED] Unix Systems Administrator [EMAIL PROTECTED] Department of Information Systems State of Arkansas 501-682-4339 _______________________________________________ Visit http://www.mimedefang.org and http://www.canit.ca MIMEDefang mailing list [EMAIL PROTECTED] http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
