These will be html and text messages - > outgoing only. Let's be a little more clear as to what numbers these are: How many subscribers? How many messages sent to the list for broadcast (not how many the list will send, but how many sent TO the list)? I doubt you wish to send 400K messages to each of your subscribers. I suspect that you have 400K subscribers etc. Notes: Recommend Mailman 2.1beta instead of 2.0.10. Your MTA will be the source of your performance problems. Spend your time there. Carefully. MTA and system tuning is a careful and detailed process. Read the FAQ. I'd generally recommend that you use a physically different system for final deliveries than the one Mailman runs on. The easy way to do this is to have Mailman deliver to localhost, and then configure the MTA on localhost to use a smarthost. > PIII 1.3Ghz dual CPU (512KB L2 cache), 512MB PC133 ECC Registered > (1x512), 2x18GB Ultra160 1rpm (RAID 1 configuration), 32MB cache > high-performance Mylex AcceleRAID controller (A170), Tyan Thunder LE-T > S2518UNG (Intel ServerWorks ServerSet III chipset), CD-ROM drive, dual > 100Mb/s FE, VGA, Dual-channel Adaptec Ultra160 SCSI controller, 400W > power supply Add some RAM. Make sure that /var/spool is mounted noatime. If you can, dedicate a physical RAID array to /var/spool that is not shared with any other partitions. You'll need more disks to do this.

[Mailman-Users] New High Performance Installation
Hello list! We've recently taken on a new client who has a very heavy list.I am wondering if anyone can shed some feedback on whether MailMan is the right answer for this! (the client is currently using ezmlm but I am trying to move away from that) The list volume is approx 400,000 emails daily. Twice a month, this will jump to 700,000 a day.These will be html and text messages - outgoing only. The hardware that this will run on is: PIII 1.3Ghz dual CPU (512KB L2 cache), 512MB PC133 ECC Registered (1x512), 2x18GB Ultra160 1rpm (RAID 1 configuration), 32MB cache high-performance Mylex AcceleRAID controller (A170), Tyan Thunder LE-T S2518UNG (Intel ServerWorks ServerSet III chipset), CD-ROM drive, dual 100Mb/s FE, VGA, Dual-channel Adaptec Ultra160 SCSI controller, 400W power supply Is anyone familiar with a MailMan installation doing this type of volume or does anyone have any advice on this install.
